Course Description Fundamentals of digital electronics: Simple concepts through medium complexity interface circuits, including number systems, logic gates, DeMorgan’s theorems, Karnaugh mapping, flip-flops, and an introduction to counters. Computer models, as well as hands-on labs, will be used throughout. Course Objectives Students will complete the following, in a manner reflecting industry practices: 1. 2. 3. 4. 5. 6. 7. Describe the difference between analog and digital signals. Determine the weighting factor for each digit position in the decimal, binary, octal, and hexadecimal systems. Convert any number in one of the four number systems (decimal, binary, octal, and hexadecimal) to its equivalent value in any of the other three numbering systems. Describe the format and use of binary-coded-decimal (BCD) numbers. Determine the ASCII code for any alphanumeric data. Identify basic logic gates and describe their behavior. Use Boolean algebra to describe simple logic functions. (continued) 8. 9. 10. 11. 12. 13. Analyze and explain the operation of basic combinational logic circuits. Analyze and explain the operation of arithmetic circuits. Identify basic latch and flip-flop circuits and describe their behavior. Analyze and explain the operation of basic sequential logic circuits. Use Multisim to model and predict digital circuit performance. Build and test basic logic circuits. Course Content and Major Topics Chapter 1: Introductory Concepts Chapter 2: Number Systems, Operations, and Codes Chapter 3: Logic Gates Chapter 4: Boolean Algebra and Logic Simplification Chapter 5: Combinational Logic Analysis Chapter 6: Functions of Combinational Logic Chapter 7 (partial coverage): Latches, Flip-Flops, and Timers Chapter 9 (partial coverage): Counters Chapter 15 (on publisher’s website; see text): Integrated Circuit Technologies Homework Assignments Homework problems are listed below. If your schedule allows, you’re encouraged to work on the problems daily, rather than save the entire set for the night before it’s due! Where applicable (i.e., calculation problems) you must show all work, indicating how you get each answer, for your set to qualify for full credit. All homework submissions must be neat, with answers boxed or otherwise highlighted, and with problems separated by a reasonable amount of white space (i.e., readable!). Incorrect solutions that show an honest effort generally will receive half-credit. Missing or essentially unworked problems receive no credit. You are encouraged to work together, and to assist those who need it. What you are strongly discouraged from doing is sharing answers with those who have not done the work. This, ultimately, hurts such students. Especially, please do not submit essentially carbon-copied sets of incorrect answers! Instead of copying bad data with the brain in neutral, discuss matters first, brain fully engaged, then submit good work! At the top of each set, clearly indicate your name (you might be surprised how often that gets left off), the course number, and set/week number (not the due date, the date you started or completed the material, or the date you submitted it). Homework sets are scored on a percentage basis and are together worth 30% of your final course grade. Late submissions will be accepted, but with a 20% penalty (based on the original score). Of course, there may be times when something happens and you’re unable to submit your work on time. If you know in advance that you’ll be absent, please inform me. And if an emergency comes up, contact me as soon as you can so we can make other arrangements. If you need help, don’t put things off; the issue isn’t going to just disappear! See Help (when and if you need it) on a later page.

These will be short affairs, with only a few problems (similar to homework problems). Quizzes are open-book, open-note, but that doesn’t mean you can just look up the answers. You still need to study! Note: If you arrive to class late, I cannot allow you to take more time at the expense of the rest of the class. As with homework, quizzes are scored on a percentage basis. These together constitute 10% of your final course grade. There is also one take-home quiz, distributed the first day of class and due the following week, that covers the syllabus (to ensure that you read it!). Exams There will be three exams in this course: two during the term, together constituting 20% of your course grade, and the cumulative Final Exam, weighted 20%. Exams are closed-book, closed-note (although there may be minor exceptions to this policy for formulas) and are scored on a percentage basis. Laboratory Experiments Each week, you will perform one or two laboratory experiments related to the current topic in the lab. Roughly half of these will be “in the flesh,” using actual components and test equipment, whereas the other half will employ Multisim circuit simulator software. Multisim is installed on NSC lab computers for your use. This powerful program is a wonderful tool for learning circuit behavior, but it is not a replacement for actual, hands-on work. If you wish, you may purchase a student copy of the program for your convenience but you are not required to do so. (The cost is about $40; see http://www.ni.com/multisim/student-edition/). As with homework, you are encouraged to work together (teams of two work best), and to assist those who need it. See the third paragraph under Homework Assignments (above) for more information. Labs will be scored on a percentage basis and are together worth 20% of your final course grade. See the fifth paragraph under Homework Assignments (above) for more information.
