      Course Rationale

      Digital Electronics course provides an introduction to the control of engineering systems using programmable logic, with specific focus on programmable logic devices. Within this context it introduces the fundamentals of digital logic, digital arithmetic, programmable logic and computer architecture. Research skills and aspects of professional practice are developed through group-based assignments. It emphasizes on techniques to design, analyse, plan, and implement complex digital systems.

      Course Objective

      The goal is to teach independently or work in a team to build simple logic circuits using basic gates as well as able to simplify Boolean functions by using the basic Boolean properties. Another goal is to teach how to design simple combinational logics using basic gates and to optimize Boolean logic using Karnaugh maps, even considering "don't care" condition. The course will also introduce the basic sequential logic components: SR Latch, D Flip-Flop and their usage and make the students able to analyse sequential logic circuits.

      Course Outcomes (CO’s)

      CO1

      Able to perform the conversion among different number systems. Be introduced to basic logic gates- AND, OR and NOT, XOR, XNOR and be able to build simple logic circuits using basic gates.

      CO2

      To implement the basic properties of Boolean algebra to simplify Boolean functions and construct circuits from them.

      CO3

      Able to minimize the Boolean functions using Karnaugh maps and “don’t care” condition. Consequently a student can then design any combinational circuits based on the real life scenarios.

      CO4

      To learn basic sequential logic components such as SR Latch, D Flip-Flop, JK Flip-Flop and their usage.
