Course Description

This course introduces logic gates to the student. Students will be able to demonstrate knowledge of combinational logic circuits and their functions. Digital electronics introduces the student to applications of “switching” circuits in logic systems. The students will be introduced to digital signals and waveforms to include TTL characteristics and logic levels. Logic networks will introduce the student to basic logic gates and truth tables.

Student Learning Outcomes

1. Distinguish between analog and digital representations.
2. Identify typical digital signals and timing diagrams.
3. Describe the property of memory and the major parts of a digital computer and their functions.
4. Perform the three basic logic operations, the Boolean expressions and truth tables.
5. Implement logic circuit using basic NAND, and NOR gates.
6. Appreciate the potential of Boolean algebra and DeMorgan’s theorems to simplify logic circuits.
7. Use either of the universal gates (NAND or NOR) to implement a circuit.
8. Describe the concept of active-LOW and active-HIGH logic signals.
9. Draw and interpret the IEEE/ANSI standard logic-gate symbols.
10. Construct and analyze the operation of a NAND and NOR Latch.
11. Understand the difference between synchronous and asynchronous inputs.
12. Construct and analyze a D-Type flip-flop and latch and JK flip-flops.
13. Analyze and apply the various timing parameters for a FF/Latch.
14. Draw the output timing waveforms of several types of fillip-flops/latches.
15. Recognize the various IEEE/ANSI flip-flop symbols.
16. Understanding the purpose of Mulitvibrators – Mono-stable, Bi-stable, and A-stable
