059-Digital Control of Second and Higher Order Systems
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
This course covers the methodology for developing a digital controller using a modern digital controls approach. Model development for both analog and digital representations are shown and performance compared. The time-shift "q" operator is introduced in accordance with the Zero-Order Hold (ZOH) behavior produced by the sampling and analog-to-digital converter used in the loop. The time-shift operator is used to produce an error predictor and model-prediction errors used to produce control equations.
A digital controller is written and used to control both digital and analog systems and the results are compared. The controller is modified to use different sampling periods and the results are compared to show the performance of the digital control over the same analog system and its dependence on sample rates. The methodology is shown to provide a fast digital controller for a high order system without a complex compensator.

The effects of discrete-time sampling of the signals is discussed, along with delay and excess phase effects in accordance with the Zero-Order Hold (ZOH) behavior introduced by the analog-to-digital converter used in the loop.
A system block diagram approach is introduced with integrators in both analog and digital forms. The original analog controller, as well as the compensator model, is produced using a bilinear-transform version of a digital integrator.

Course Description:
The Switchmode Buck converter is used widely for high efficiency conversion of DC power available at a higher voltage and delivered to a load at a lower voltage. This course develops models of the Buck converter with current-mode control. Basic operation, a practical set of examples, and large/small signal models are discussed. The considerations for feedback regulation and load-current limiting control of the converter are introduced.
The selection of appropriate inductor and capacitor values are discussed, considering the frequency of operation and other design parameters. A constant-frequency Pulse-Width Modulator (PWM) controller is employed for pulse-by-pulse peak-current control. And a method for constructive use of inductor parasitics is employed for current monitoring. We introduce the peak-threshold current control in the open-loop model to illustrate a current-limit function, and then develop that control into the pulse-by-pulse current-mode control for voltage feedback. We develop the feedback conditions for frequency-domain, small-signal, stability in the open-loop model and include a Pole-Zero (PZ) compensator for good margins. We introduce the Zero-Order-Hold (ZOH) effects of the inherent sampling caused by cycle-by-cycle control and include those effects in the (PZ) compensator. The loop is closed and a "soft-start" capability added to avoid current-limiting during startup. Line and load regulation is shown for the example as well as transient load recovery. Finally, the need for "Slope Compensation" in some designs is discussed and a means for adding it is shown.

Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
This course introduces both analog and digital communications concepts and some of the reasons for the migration from analog to digital technologies. Pertinent analog signal and system concepts are reviewed for comparison and contrast to corresponding digital concepts. Digital representation of analog signals is introduced in both the time and frequency domains so that analog transmission of digital signals could be compared.
Versions of "Suppressed Carrier" modulation progressing from the original Weaver modulator architecture are developed for "Single-Sideband, Suppressed Carrier" analog voice applications through variations to other applications. We add phase modulation and amplitude modulation to the Weaver architecture showing the development of quadrature techniques for using both upper and lower Weaver sidebands to produce independent "I" and "Q" communications channels. Only one bit of information is discussed for each of the phase modulation and amplitude modulation in a simple QAM example, but the groundwork is laid for extending the system.

This course introduces both analog and digital communications concepts and some of the reasons for the migration from analog to digital technologies. Pertinent signal and system concepts are reviewed for comparison and contrast.
The course develops the theory and practical issues and examples leading up to Direct Sequence Spread Spectrum (DSSS) Communication. The information theoretic foundation for trading bandwidth and improved Signal-to-Noise Ratio (SNR) is introduced mathematically, but other useful properties associated with particular spreading sequence properties are introduced by example. The gradual development based on the Weaver architecture for frequency translation of single-sideband, suppressed carrier signals through digital QPSK examples into pseudo-noise (PN) sequence spreading of QPSK of sub-carrier sidebands and finally to direct-sequence, spread-spectrum QPSK is employed to build awareness of the relationships between the spectral energy and the modulation processes. The PN sequence generation, its auto-correlation and cross-correlation attributes are introduced and employed in example with a justification for the development of the matched-filter/correlator approach to sequence de-spreading. Some issues of carrier synchronization and problems are introduced but not developed in detail. Finally, the statistical properties of the correlator approach are shown to be the basis for Code-Division, Multiple Access (CDMA) spectrum sharing to ameliorate the extra bandwidth occupied by the spreading.
The practicing engineer should be able to understand the important issues of DSSS digital communication and choose system components in a meaningful way on completion of the course.

This course introduces the Phase-Lock Loop (PLL) with considerations from classical feedback theory producing a simple analog loop for demonstration purposes. The components are analyzed, linearizing them as required and showing the second-order nature of the loop with the PZ compensation filter for stability. The PLL capability as a Frequency-Shift Keyed (FSK) receiver demodulator for a Frequency-Modulated (FM) signal is demonstrated.
The Costas Loop variant of the PLL for double-sideband, suppressed-carrier synchronization using a Bi-Phase modulated signal is introduced, as well as the "Double-Loop" variant of the Costas Loop, showing the equivalence of the saturated signal paths for the Bi-Phase modulation in a summing loop, and the requirements for a difference term for Quadri-Phase Shift Keyed (QPSK) signals. The 180° phase uncertainty associated with the receiver synchronization is shown and discussed.
A digital PLL for frequency synthesis applications is demonstrated with the relationships between loop bandwidth and channel spacing shown. The "Exclusive-OR" logic function is demonstrated as a phase detector and the Phase-Frequency Detector (PFD) and Sink-Source-Float (SSF) implementations are introduced. The stability requirements for the components and the design of a PZ compensator for the digital PLL, including the use of a transconductance and impedance for loop filter application are discussed.
The effects of the sampling delay on the magnitude and phase characteristics of the loop are discussed.
The time and frequency domain performance of a macro-model using the parameters developed show that the discrete-time performance is well predicted, but that there are noise effects from the PU/PD pulses in the PFD.
Fractional-N synthesis technique is introduced and contrasted between the averaging and Δ-Σ modulator approaches to the oversampling used in the Fractional-N approach.
The engineer who completes this course should be able to design a working Phase Lock Loop, making it stable for their application.

A single pole circuit is introduced and responses analyzed in the frequency domain and time domain. An ideal delay is introduced for comparison and sets a reference for step response behaviors.
Polynomial root locations are described in the complex s-plane and complex conjugate pairs plotted and described using (w0, z) notation as well as (t0, Q) notation. Phasor notation is introduced for evaluation of steady-state sinusoidal excitation of transfer functions. Second-order, complex conjugate pole pairs are introduced and the asymptotic behaviors developed and contrasted to the single-pole behaviors in magnitude, phase, and group delay attributes. Straight-line approximations are produced and the errors of approximation discussed.
Classical Butterworth, Chebyshev, and Bessel filters are introduced and the construction formulae developed. The Cauer filter is also illustrated, but mathematical development using elliptic functions is not included. Frequency domain and time domain responses are developed using a 4th design form as representative of even-order forms and a 5th order design as representative of odd-order forms. Only the 5th order Bessel filter example is synthesized from the equations. A 5th order equalizer is examined for the 5th order Chebyshev and Cauer filter and shown to provide equivalent results for both Chebyshev and Cauer filters. An additional pole pair is added to the 5th order equalizer and the justification and improvements noted. Transformations are discussed to convert low-pass prototype designs to high-pass and band-pass filters.
The course is designed for a practicing engineer seeking a capability for designing and specifying filters and equalizers for frequency domain and time domain applications.

087-Embedded Systems; Analog, Digital, and Microcomputers
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
This course traces background history leading to current "Embedded Systems" from the introduction of system classification concepts through modern digital computer concepts, and first-practice digital computer embedded systems leading up to the current methodologies, tools, and practice involved in the design of Embedded Systems.
The digital computer hardware is traced from the vacuum-tube era through the advances of solid-state technology to today's integrated circuits. The software is shown in parallel with introduction of abstract languages, operating systems and "hard" real-time software, program code and library practices, through C-Code editing, compilation, and system building. Hardware Design Language (HDL) concepts are introduced in the context of adding digital functionality to the included microcomputer capabilities.
A Top-Down design methodology is used in the context of Embedded Systems development with both open-source and proprietary tools from an Engineering System Level (ESL) through an implementation at the demonstration-board level with two different examples. The design-flow through the use of tools is discussed prior to the example use of those tools so that the "big picture" is seen first. A simple Delta-Sigma (DS) analog-to-digital converter is used as an analog/digital or mixed-signal example with some modeling and simulation relating to the analog functions and some relating to the digital functions. The use of the top-down approach makes the system simulation of behavior clear prior to the "binding" of the functions to analog or digital components.
Two different implementation hardware boards: the BeagleBoard featuring a Texas Instruments (TI) OMAP™ IC with an ARM processor and TI proprietary Digital Signal Processor (DSP) onboard, and Cypress Semiconductor PSoC5™ with an ARM processor and proprietary configurable analog and digital blocks on a "First Touch" board are introduced as a hardware target candidates.
Software development tools are introduced and representative usage shown for both open-source and proprietary tools using a C/C++ path in both an open-source Linux environment and a MicroSoft Windows™ environment. Code generation automation is discussed and manual code entry discussed in the context of the tools.
The example system is explored in detail from within the context of the Cypress Semiconductor PSoC5™ "First Touch" environment with some alternatives introduced. The steps necessary and the code example for the PSoC5™ "First Touch" environment are referenced, as well as the necessary hardware and software requirements to enable the example in the BeagleBoard are shown and links provided to obtain the accelerometer, display, cables, and software required. The MathWorks PolySpace™ semantic run-time code checker software is shown with illustrations of the checking capabilities.
A 50% discount coupon on products from Cypress Semiconductor Corporation is included with this course.

102-Memories in Computers — Part 1: Overview and DRAM Introduction
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
Modern computers include many types of memories, including magnetic hard drives, Flash memories, Static Random Access Memories (SRAM) and Dynamic Random Access Memories (DRAM). The characteristics, advantages and limitations of each of these memory implementations are described and compared. The most important of these memory types is DRAM, and this course takes you inside the DRAM so you can understand how it operates and why it is the largest selling integrated circuit ever invented.
DRAMs were a $38B (USD) business in 2010, and appear in every computer (PC, Mac, tablet, laptop, desktop, server or mainframe) and home gaming console (PlayStation, Xbox or Wii). DRAMs first appeared on the scene in 1970, introduced by a small start-up company called Intel. Today they are a commodity, produced by companies all over the world in essentially interchangeable form.
Both the original DRAM architecture, called the asynchronous DRAM, and the higher speed synchronous version, the SDRAM, are discussed in detail. You will be introduced to the concepts of refreshing, access time, multiplexed addresses, fill frequency, CAS latency and burst length. No math beyond simple arithmetic is required.

111-Memories in Computers — Part 2: DDR SDRAMs
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
As the largest dollar volume portion of the semiconductor industry, memories appear in every computer, printer, home game console and car; as well as a growing number of home appliances. Total memory sales were $124B in 2017, out of $412B worldwide semiconductor sales. DRAM sales alone grew by 77% in 2017, to a total of $72B. But memory demand is cyclical. 2018 saw DRAM sales of almost $100B, the highest ever. 2019 sales dropped to $62B; 2020 sales were $67B; and 2021 revenue soared to $98B.
Since the late 1990s, four increasingly capable Double Data Rate (DDR) Synchronous DRAM architectures have evolved. The first generation, DDR, doubled the rate of information flow to and from the memory device as compared to single-data-rate synchronous DRAMs. To meet the resulting very tight timing requirements, a new circuit called the delay locked loop was introduced.
The second generation, DDR2, added several features to improve device usability. In particular, on-die termination (ODT) improved signal integrity and reduced external component count.
The third generation, DDR3, provided a refined ODT capability and further defined external device timing in terms of clock cycles instead of internal device parameters.
The fourth generation, DDR4, continued increasing storage capacity and improving the rate of data transmission. But it also emphasized reducing power by many architecture modifications and feature additions.
The fifth generation, DDR5, built on DDR4 with more storage capacity, faster data rates, and reduced power. DDR5 added a new capability, on-chip error correction (ECC).
This course discusses the characteristics and advantages of each of those architectures in a clear and concise manner that any technically trained person can understand. You will be introduced to and become familiar with concepts such as CAS latency, burst length, delay locked loops, on-die termination, prefetch, mode registers and redundancy. Memory packaging in dual in-line memory modules (DIMMs) is also discussed.
This course builds on, but is independent of, Memories in Computers—Part 1. No math beyond high school algebra is required.
112-Memories in Computers — Part 3: Flash Memory
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
Flash memories will account for $26B in sales in 2010. They are used in all modern digital cameras, camcorders, cell phones, PDAs, music players, home video game machines and computers.
Why is flash so popular? Flash excels in three areas: technical, physical and financial. The technical reasons are (1) nonvolatility–flash memory retains its information for more than 10 years even with no power applied and (2) speed–flash memory is 100 to 1000 times faster than magnetic hard drives. The physical reasons are (1) density–flash memory has 8x as many bits per chip as DRAM, and (2) power–flash memory consumes far less power than magnetic hard drives. In the financial area, flash memory is about 40% of the cost of DRAM on a per bit basis.
Why isn't flash memory used in place of DRAM and magnetic hard drives? Again, there are three areas that hold back flash: reliability, speed and cost. Regarding reliability, flash memories can endure from 5000 to over 100,000 erase/program cycles. That is adequate for many but not all applications. Flash speed is indeed much faster than magnetic hard drives, but programming speed is far slower that DRAMs; much too slow for main memory applications. And flash cost, although lower than DRAMs, is still far above that of magnetic hard drives.
This course discusses all of the above issues, as well as the historical background, physical basis, cell structure, and chip architecture and operation of these omnipresent devices. You will learn and understand hot electron injection, Fowler-Nordheim tunneling, NOR and NAND array structures and operation, multi-level storage and error correction coding. The flash memory market, including applications and major producers, are explored; and two major portions of that market, flash memory cards and solid state drives, are examined in detail.
This course builds on, but is independent of Memories in Computers–Part 1. No high-level math is required.

181-Introduction to Small-Scale Wind Project Design
4
List: $90.00
Sale: $39.95
Course Objectives: 1. Summarize common terminology of the different types of wind turbines, as well as their relative merits and shortcomings.
2. Use the �Fundamental Equation of Wind Power� for realistic back-of-the-envelope power output projections and identifying practical limitations.
3. Familiarization with the nature (but not the detailed mathematics) of typical wind distribution regimes, such as the Weibull and Raleigh distributions.
4. Cognizance of wind energy project planning issues and show-stoppers, which if initially overlooked, could result in project cancellations.
Course Description:
This course covers the fundamentals of Wind Power technology, providing a practical "quick study" to those who need to (or desire to) become knowledgeable on this topic. Professional Engineers often find that they themselves need to "get real smart, real quick" on wind power, since it is not unusual that they are often the first to be asked by a client or employer to assess if more energy, time, or money should be devoted to investigating the feasibility of a proposed wind project.
By successfully completing this course, you should be comfortable performing fundamental wind energy projections with the sparse and incomplete data often available during preliminary project discussions, as well as become cognizant of pit-falls and show-stoppers that plague initial forays into this field. The goal is to equip the student so he or she will be able to provide a technically-sound reply when asked if a proposed wind power project warrants further evaluation at some additional effort or expense.
Note: This course has been approved for 4 GBCI CE hours for LEED Professionals; GBCI Course ID: 0920018312
182-Feedback Control System Fundamentals
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
This course discusses many fundamental concepts associated with classical feedback control theory. Feedback control measures the state of a physical system or device with a sensing system. The measured state is fed-back and compared to a desired state and the error used by a controller to reduce the difference between the actual and desired states. An example of a feedback control system is the central heating and air conditioning system for a home, or building. A thermostat or temperature sensor is the feedback sensor that measures the room temperature and compares it to the desired temperature or set point, calculating a difference or error. If the temperature is less than the set point, the error is used by the controller to force more heat into the room. When the set point is reached, the error is zero or below an error threshold and the controller will stop heating the room. Another example is the speed control in most of today's automobiles. The speed of the vehicle is measured and compared to a desired speed. Based on the difference between actual speed and the set point, acceleration or braking is applied to the automobile drive to null the error and maintain the desired speed.
Classical control deals directly with the differential equations that describe the dynamics of a plant or process. These equations are transformed into frequency dependent transfer functions. The transfer function is the ratio of two frequency dependent polynomials whose roots describe the response of the plant in a frequency domain. The controller or compensator shapes the closed feedback loop response, given the plant response, to achieve the control performance objectives. Classical feedback control design and analysis tends to require a good foundation in mathematics, however the purpose of this course is not to dwell on the math, although examples are provided, but to provide the basic design and analysis concepts.
The topics covered begin with a description of the basic block diagram in section 2. The relationships between time and frequency domain representations of the block diagram elements are discussed in section 3 followed by the key feedback relationships derived from the block diagram algebra in section 4. Control loop stability and methods to determine stability margins are described in section 5 followed by a discussion of specifying control loop performance in section 6. A couple of control loop design methods are provided in section 7. The basic theory is then applied to two examples; a home heating system in section 8 and motion control applications in section 9. Converting to a digital sample data controller is discussed in section 10; as related to the motion control example in section 9.

4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
With the recognition of the Professional Engineering status for the practice of Computer Engineering in April of 2009, the practice of Control Systems Engineering in October of 2011, and the practice of Software Engineering in April of 2013, there has been the need for specialized continuing education courses related to these practices. Computer Engineering majors may have taken a course with some component of digital design without using Verilog, or may have had a course using the VHDL language. Control Systems engineers will find Verilog to be a useful tool for modeling and simulating real-time hardware and embedded systems for control applications, Software engineers can apply the principles of the concurrent parallel system representations available in Verilog for numerous applications. Other disciplines, including Electrical Engineers will also find the digital design practices encapsulated in Verilog useful all the way to the device level representations available in the language.
We assume that all readers are familiar with digital design concepts, but are interested in an introduction to the capabilities of the Verilog Design Language and how to use it in the design practice. Likewise, we assume that readers generally have rudimentary experience with computer languages, text editors, and general concepts of computer program compilation.
We lead the reader through installation of Free, Open Source Software tools to enter designs, compile and display results, then take the reader through the Behavioral, RTL, and Structural levels of abstraction available, illustrating with simple examples. This course is not exhaustive on the topic but makes a case for the value and usage of Verilog in Digital Design.

291-Proportional, Integral, and Derivative Controller Design Part 1
4 $90.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
In this course, the design and application of Proportional plus Integral plus Derivative (PID) controller's is discussed. Some familiarity with feedback control may help in providing a better understanding of the course material. PID control is a technique used extensively in feedback control systems. Its origins date back to the 19th century, being used for governor speed control, and since then in numerous applications with a wide variety of actuators and sensors. The controller is simple structure; being the sum of three terms as the name implies. The PID structure provides for a fairly wide range of tuning adjustment in a feedback control loop, especially for relatively simple processes. A PID uses the error, it's integral and derivative to derive a control signal driving the error to a null state. The controller can be structured in many configurations; P-only, PI, PD, PID, plus others to be discussed. PID control is central to most process control systems; but can also be found in numerous applications other than process control ranging from positioning control loops to pointing, tracking and platform stabilization control loops. The PID can also be integrated with higher level control strategies such as model predictive control, adaptive controllers and fuzzy logic control described in Part 2 of the course.
Starting with an introduction in section 1.0, topics covered are a description of the basic feedback control loop block diagram in section 2 and how the PID relates to the control loop. The relationships between time and frequency domain representations of the block diagram elements are discussed in section 3 followed by the key feedback relationships derived from the block diagram algebra in section 4. The PID control algorithm is described in section 5 which includes the frequency domain characterization of the PID (5.1), the effect of each PID term has on response (5.2) and finally different forms of the PID used in actual applications. In section 6 a discussion of specifying control loop performance is presented. PID control loop design methods are provided in section 7. The basic theory is applied to an example; a home heating system, in section 8.

358-Sightline Control Basics for Geo-Pointing and Locating - Part 1
4 $90.00
Course Objectives: Describe theory and system level architectures
Course Description:
This is a three part course discussing geo-pointing and locating. With the proliferation of unmanned aerial vehicles (UAV) coupled with advancements in camera and inertial measurement sensor technology; this is fast becoming a technology used in many applications requiring geo-referenced imagery. Historical applications for military and civilian surveillance and navigation are fairly well documented and continue to grow. But the
technology is now the cornerstone for numerous situational awareness applications such as environmental, fire protection, road/bridge surveillance, maintenance and protection. It may even be part of your pizza delivery service, which for those of you with bevy of children could be a sobering thought.
The course is organized as three topics; the first addresses generic sightline control (SLC). As geo-locating requires geo-pointing and pointing requires maintaining a stable line of sight (LOS) to a targeted object or area, then an understanding of SLC is important. The second topic focusses on the geo-pointing problem given a stable sightline to the object to be geo-located. Finally the basics of geo-location, using direct and image geo-registration, are described. Many SLC sections in Part 1.0 require some background in control theory as well as mathematical operations with vectors and matrices. For those interested in geo-pointing and location at a system level; these sections will be somewhat tedious. However, it is not essential to follow all the math but it is important to understand the need for it and how it plays into an overall solution. Similarly there is a lot of detailed discussion on pointing techniques, for example one section is dedicated to using mirrors for pointing. The details may not be critical, but it is important to understand that with all the benefits obtained using a pointing mirror, they also have characteristics that must be understood and accounted for in the design or one will be in for a rather unpleasant surprise. Pointing design should follow a top down design procedure; beginning with requirements through HW and SW design and implementation. However given cost and schedule constraints, one is often forced into an off the shelf design with compromised performance. Understanding the design requirements, however, should not be compromised so related performance can be quantified and improved in future designs. The purpose of the course is to lay a framework for understanding this design process. There should be sufficient math detail for those interested at the equation level but hopefully adequate course structure for those not so inclined to still follow the overall design process. Test questions are at a system level. The course has a two part structure; Part 1.0 covers SLC basics and geo-pointing, Part 2.0 provides a brief review of Part 1.0 followed by a focus on geo-locating, and finally Part 3.0 describes camera sensor characteristics and requirements for geo-locating.
359-Sightline Control Basics for Geo-Pointing and Locating - Part 2
4 $90.00
Course Objectives: Describe theory and system level architectures
Course Description:
This part of the course will apply the sightline control (SLC) fundamentals described in Part 1.0 to the geo-pointing and location problem. Initially Section 1.0 Part 1.0 is reviewed, particularly pointing performance
requirements which directly impact geo-pointing and location performance. Geo-pointing is then described, effectively delving deeper into the material begun in section 8.0 in Part 1.0 of the course. Geo-pointing errors are related back to the SLC pointing problem with its limitations serving as a foundation for pursuing different geo-location approaches. Geo-location techniques are generally categorized as either direct or image geo-registration derived. The errors associated with the pointing solution for direct geo-pointing provide a basis for examining geo-location techniques that use image geo-registration to improve performance.
Image geo-registration is also used in many applications that require geo-referenced sensed imagery as well as location; discussed in Section 4.0 of Part 2.0 of the course. As this is effectively a technology in itself, only the salient aspects of the process are reviewed but should provide a source for further study and investigation, if of interest. Regardless of the geo-location technique used, however, geo-pointing will generally be part of the solution. If not the solution, it will provide coarse location estimates for the image geo-registration process. A substantial amount of image spatial processing is required to obtain an accurate solution to an image geo-registered location and the processing is described at a functional system level to capture the overall design process. The benefits that image geo-registration provides beyond that of location are significant since it can used to obtain situational awareness as defined for many applications. Military and civilian surveillance is an obvious application, but even the use of image information within the transportation infrastructure for highway and bridge maintenance management, damage and structural deterioration assessment, traffic pattern analysis and control, etc. is a growing application. The goal of this part of the course is to provide a system level functional description of the geo-location process and how performance relates back to that of geo-pointing with SLC. The camera sensor requirements for image geo-registration location are discussed in Part 3.0, the last part of the course.
360-Sightline Control Basics for Geo-Pointing and Locating - Part 3
2 $45.00
Course Objectives: Provide design algorithm approach for geo-pointing and locating providing a basis more detailed design
Course Description:
This final part of the course discusses sensor characteristics and requirements for geo-location image geo-registration, as described in Part 2.0 section 4.0 of the course. The focus is primarily on cameras and sensors whose response is in the visible and near infrared wavelength spectrum. Sensor characteristics that drive sensitivity and noise as well as camera sensor and optics parameters that determine scene coverage and resolution are all reviewed in this section. In total the three part course should provide an overview of geo-pointing and locating sufficient to plan for such an application and detailed design areas that require further investigation and study to perform an actual design.

366-Resiliency Strategies for Smaller Scale Sites
2 $45.00
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Course Description:
The purpose of this course is to explore different options that are available for helping to make smaller scale sites more resilient and adapted to better handle the larger, more frequent storm events. Resiliency is usually thought of being done at a much larger scale; municipalities and states implementing large scale strategies that are focused at making their target areas more resilient and less susceptible to large storm events or rising sea levels. Those large-scale resiliency projects are often complicated and very expensive; therefore, it doesnt seem like there is much that can be done on a smaller site. In the course, however we will exam some of the ideas and strategies that are implemented on a large scale and see how they can be scaled down to be viable on a smaller site. We will also review other strategies that can be implemented to make a site better situated to withstand or minimize the impact of a large storm event. It may not be feasible to completely protect a site and its infrastructure by itself, however we will review design strategies and actions that can mitigate or reduce impacts from large storm events, flooding, and sea level rise. There are both physical and operational changes for almost every budgetary range that can be made to make a site more resilient and better protected from rising sea levels, flooding and larger, more frequent storm events.

The central processing unit (composed of the arithmetic logic unit, registers and the control unit) functions as the brains or core of the processor. The central processing unit processes machine code stored in memory to control all of its functions. The machine code is compiled or assembled from the processor’s instruction set which defines all of the operations of the microcontroller. To complement their functionality, microcontrollers include a suite of peripherals such as input/output pins, timers, a real-time clock and communications controllers.

Here I will discuss how to design a simple circuit incorporating a microcontroller with a small footprint, small pin count, and a small amount of internal memory (both program and data memory). I will give program examples using the C programming language.
Microcontrollers are simply microprocessors that include program and data memory and peripherals such as general-purpose input/output ports, timers, serial communications controllers, analog-to-digital converter, etc.
Course Summary
The Atmel ATtiny2313A microcontroller used for these exercises is packaged in a 20-pin DIP package. It is small compared with other microprocessors available, but there are other smaller devices available. For example the Atmel ATtiny10 is packaged in a 6-pin SOT-23 package, making this device ideal for small projects such as an electronic candle to simulate the flicker of the flame or a child's shoe that has LEDs that light up when he or she walks.
Although the Atmel AVR series of microcontrollers is a great product offering many features with a powerful core, this course is not meant to be an advertisement for the Atmel AVR series of microcontrollers. There are many similar microcontrollers available on the market, such as the Microchip PIC, Texas Instruments MSP430, Intel 8051, STMicroelectronics STM8, Freescale 68HC11, and multiple versions of the ARM core from many vendors.

508-Moore's Law: Rise of the Machines
2 $45.00
Course Objectives:
Course Description:
Moore's Law is a term used to describe the increase in computing power over time. Moore's Law is the observation that the number of transistors on an integrated circuit (or microprocessor) doubles every two years. This course describes how Moore’s Law has proven true for the past fifty years and discusses how the computing industry will have one of two fates. Either the increase in computing power over time will eventually level off due to physical limitations or further advances in computing power will allow processing power to exponentially increase. Could this exponential increase in processing power eventually lead to a technological singularity?
Learning Objective
At the conclusion of this course the student will learn:
• the definition of Moore's Law
• how Moore's Law has affected the semiconductor industry
• what visionaries say about the future of technology
• the definition of a technological singularity
Intended Audience
This course is intended for all engineers.
Course Introduction
Advances in technology throughout human history have never been as evident as the advances in computer technology in the latter half of the twentieth century and the early part of the twenty-first century. Technological progress is no longer seemingly liner; it is clearly exponential. The trend in the increase in computational power is predicted by Moore's Law.
Moore's Law is a term used to describe the increase in computing power over time. Moore's Law is the observation that the number of transistors on an integrated circuit (or microprocessor) doubles every two years.
A transistor is a tiny semiconductor device used to switch electronic signals. A transistor is a simple digital switch. When used in a digital circuit the transistor is either on or off.
Logic gates build on the switching power of a transistor to make more complex building blocks. A logic gate is the fundamental building block for a digital integrated circuit, and the fundamental building block for a logic gate is the transistor. Logic gates include AND, OR, NOT, NAND, NOR, XOR. All of these logic gates can be built using only NAND gates. This simplifies and reduces the complexity of integrated circuits by only using one basic type of logic gate. NAND gates can be assembled to form flip flops (like the D flip flop); these flip flops are called registers and form the basis of microprocessor cores. The heart of a computer is a microprocessor, and microprocessors are built from logic gates and the basic building block of a logic gate is a transistor.
Course Summary
Moore's Law is a term used to describe the increase in computing power over time. Moore's Law was introduced in 1965 by Gordon Moore. Moore's Law is gauged by the maximum number of transistors on a microprocessor or memory chip at any given point in time. He stated that the number of transistors on an integrated circuit will double approximately every two years. Whether held up by the accuracy of Moore's visionary prediction or driven by industry’s thirst to keep up with the trend in technology, Moore's prediction has proven to be true for almost five decades.
This exponential computing trend has affected all avenues of life including (by not limited to) the following: personal computers, communications, transportation, navigation, agriculture, medical, world finance, education, and social media. Some industry experts believe Moore's Law will reach a fundamental limit within the next few decades, while others expect a revolution in the microprocessor technology to maintain the trend.
Many visionaries feel that we humans will soon reach a point in our existence that can be described as unpredictable and maybe even unsettling. This point in history (if the predictions are true) will be the result of an intelligence explosion caused by a technological singularity. A technological singularity is the point in human history where life or even existence after the event which is based on technological progress is unpredictable or incomprehensible.
These are only predictions though. The fact of the matter is this: we don't know. We don't know enough about consciousness to apply the concept to a machine (yet) if it is even possible...
509-State Machines
2 $45.00
Course Objectives:
Course Description:
An electronic lock, a vending machine, a subway turnstile, a control panel for a microwave oven, a spell checker, a text search application, and the core of a microprocessor all embody a common element. Their behavior can be modeled using a finite state machine. A state machine is a model used in a design to visualize the effects of a sequence of inputs on the state of the system and its output. The behavior of the system is predetermined from its design. A state machine is one of the most common building blocks of modern digital systems.
Learning Objective
At the conclusion of this course the student will learn:
• When to use a state machine in a design
• The differences between a Mealy machine and a Moore machine
• The different components of a state machine
• The difference between a state diagram and a state table
• The advantages and disadvantages of a state machine implemented in hardware
• The advantages and disadvantages of a state machine implemented in software
Intended Audience
This course is intended for all engineers.
Course Summary
A state machine is a model used to describe the behavior of a real world system. State machines are used to solve a large number of problems. They are used to model the behavior of various types of devices such as electronic control devices, parsing of communications protocols and programs that perform text or pattern searches.
State machines may be described using a state diagram and a state table. A state diagram is composed of states, inputs, outputs and transitions between states. A state table describes a state machine with the present state and input on the left and the next state and output on the right.
State machines may be implemented using either a hardware architecture or a software architecture. The advantage of a hardware implementation is that it operates very fast, but it is difficult to modify and usually requires more circuit board space. The advantage of a software implementation is that it is easier to design and modify, but can be slower than the hardware equivalent.
510-Error Detection in Digital Systems
2 $45.00
Course Objectives:
Course Description:
Information theory is a branch of applied mathematics and electrical engineering involving the quantification of information. When Claude Shannon developed information theory in 1948, thus ushering in the information age, he introduced the concept of entropy to information. This entropy or shortage of information in a message is what gives rise to errors in the data. Most communication systems and data storage and processing systems are unreliable to some degree, which means that errors may be introduced in the communications channel or while retrieving data from a memory device. These errors must be controlled.
The purpose of this course is to describe four different error detection techniques and to discuss the advantages and disadvantages of each. This course describes the parity check method as well as the checksum and cyclic redundancy check (CRC) methods. It describes hash functions and when they should be employed. This course also briefly discusses error correction techniques.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
Learning Objective
At the conclusion of this course the student will learn:
• Four different error detection techniques
• How to compute odd parity and even parity for a sequence of bits
• How to compute a checksum for a given block of data
• How to compute a CRC for a given block of data
• The benefits and drawbacks of a parity check, checksum and CRC
• How a cryptographic hash function is used to ensure the integrity of a software program or electronic document
Intended Audience
This course is intended for all engineers.
Course Introduction
We are exposed to a lot of information every day, from viewing content on a website on the Internet to listening to a song on our smart phone. This information (or data) is constantly stored, transmitted and processed. It is important that the data is correct or relatively error-free. Some amount of error is acceptable, depending on the application. For example, a few bit errors in a music data file in an MP3 format are acceptable, but a few bit errors in the data being transferred to the flight controls of a rocket could be catastrophic.
Course Summary
The use of a parity check is perhaps the simplest form of error detection. With this technique a bit is inserted after a fixed number of bits to maintain either an odd number or an even number of bits. A checksum in which all of the bytes in a given block of data are XORed to produce a checksum value can be appended to a block of data before it is transmitted. When a block of data is received the checksum is recomputed and checked against the one just received with the block of data. Checksums (either ones that are XORed or a running sum) are weak compared to a CRC. A CRC is used in the same manner for error detection as a checksum, but are more robust because the value of the CRC depends on the order of the data.

519-Digital Design: Combinational Logic
5 $112.50
Course Objectives:
Course Description:
You will encounter digital circuits multiple times in any given day. Digital circuits have infiltrated society in ways unheard of only a few decades ago. They are everywhere and seem to be in everything. Without them we would have no microprocessors. Without microprocessors we would have no computers or smartphones or sophisticated fifth-generation fighter jets or even something as simple and convenient as a coffee maker that brews the coffee before we wake up that shuts off automatically when we forget to turn it off. Maybe we could still design a coffee maker with an analog clock with a mechanical switch that will shut off the hot plate when the clock advances forward past a mechanical set point, but the point is that these little devices (digital circuits) are commonplace and here to stay.
Digital circuits are comprised of tiny little on/off switches called transistors. The transistor is the building block of all digital circuits. This revolutionary little switching device was invented in 1947 and its creators were awarded the Nobel Prize in Physics a few years later, and rightly so. Only a few other inventions have impacted and affected our lives in so many ways.
Transistors can be organized into logic gates. The most basic gates are AND, OR and NOT. With these fundamental gates, all other gates can be built. Boolean algebra describes logic gates in symbolic form which gives a designer the ability to design a complicated logic circuit using math by forming equations. These equations are directly transformed into logic symbols and into a logic circuit. Connecting several logic gates together forms something called combinational logic. With this combinational logic, adders can be fabricated as well as encoders, decoders, multiplexers and demultiplexers. A multiplexer is a device that allows one input to be selected from several inputs. An arithmetic logic unit (ALU) is a multiplexer which is at the heart of a microprocessor's core.
This course is intended to be a review of the basics of digital logic starting with the binary numbering system, hexadecimal numbering system, logic gates, and logic circuits.

603-Microcontrollers: the Arithmetic Logic Unit
4 $90.00
New Course
Course Objectives:
Course Description:
The arithmetic logic unit (ALU) is the central core of a central processing unit (CPU). The ALU is simply a digital circuit that performs arithmetic and logical operations on binary numbers. They are combinational logic circuits which means that their outputs change asynchronously in response to changes to their inputs. ALU circuits perform operations on integer binary numbers. All microcontrollers contain an arithmetic logic unit (ALU). It is a fundamental building block of the CPU.
An ALU has two integer inputs called operands and another input called an opcode. The opcode instructs the ALU which instruction to perform (like addition, subtraction, decrement, increment, AND, OR, NOT, XOR, etc.). The opcode code is a binary code that comes from the instruction set (or program) that is being executed. The instructions or program will contain both the operands or numbers to be used and the opcode that tells the ALU what to do with the numbers, eg. add the numbers. These instructions are usually written in a higher level programming language and are stored in the computer's main memory. A compiler will compile the higher level language program and convert it to machine code. The computer executes one instruction at a time.
This course focuses on the ALU. This course explains how arithmetic and logical operations are performed within a CPU. This course explains how the instruction from the machine code from a compiled computer program gets translated into useful code for the ALU to determine which operation to perform and where the data is coming from.
Learning Objectives
At the conclusion of this course the student will learn:
• how an ALU selects its different functions
• how ALUs were designed in early computers
• how an ALU uses its operands
• how an ALU uses its opcode
• how an ALU performs subtraction
• how a full adder works with carry in and carry out
• the difference between a half adder and a full adder
• the logic diagram of a full adder
• how to describe an ALUs operations with a truth table
• how an instruction set is converted into machine code
• how machine code is decomposed into an opcode that configures the ALU for a particular operation
• how an ALU is integrated into a CPU
• how the fetch-decode-execute cycle works in a CPU
• the significance of the 74181 ALU in early computers
• how many arithmetic and logic operations that a 74181 ALU can perform
• the schematic and truth table of the 74181 ALU
