Semester: I

Course Description: This course covers the concepts of digital logic and switching networks.

The course includes the fundamental concepts of boolean algebra and its application for circuit

analysis, multilevel gates networks, flip-lops, counters logic devices and synchronous and

asynchronous sequential logic and digital integrated circuits.

Course Objectives: The main objective of this course is to introduce the basic tools for the

design of digital circuits and introducing methods and procedures suitable for a variety of digital

design applications.
