Course Summary

This course is a lecture course and is taken by all students taking the third year of electronics and/or electrical engineering degree in Semester 1. It comprises one 22 lecture module. Digital System Design 3 aims to build on the material presented in the second year and enhance students understanding and design skills of combinational and sequential digital circuit design techniques. To introduce the concepts and techniques for datapath and FSM design.
