DIGITAL ELECTRONICS
Course Description &amp; objectives:
With this course, students will learn different number systems, and their
applications. Also, Students will learn to appreciate the design of the basic
logic circuits, components used inside the computer.
Course Outcome:
1. Students will be able to represent numerical values in various number
systems and perform number conversions between different number
systems.
2. Able to analyze and design digital combinational circuits like decoders,
encoders, multiplexers, and de-multiplexers including arithmetic
3. Able to analyze sequential digital circuits like flip-flops, registers,
counters.
4. Knowledge of the nomenclature and technology in the area of memory
devices: ROM, RAM, PROM, PLD, FPGAs, etc.
5. Understand the importance and need for verification, testing of digital
logic and design for testability.
