EC25C07:

Digital System Design

Course Objective:

This course aims to create a strong foundation for Digital Electronics. The students are taught the basic components of digital systems and the processes of their implementation. The students are also taught Boolean algebra, logic gates, the basics of memories, and the implementation of combinational and sequential digital circuits using logic gates. Students are trained to employ the principles of digital electronics to implement digital design for the given problem.
