What you’ll learnVIEW COURSE VIDEOS

The course is intended as an introduction to digital logic and systems. At the end of the course, students should be able to: understand and explain digital systems composed of basic combinational and sequential elements
understand issues with timing and the performance analysis of circuits
understand the use of finite state machine based controllers and their use in design of complex circuits
understand the basic operation of a microprocessor in terms of a datapath and programmable control, along with memory interfacing
