AIM
To introduce the fundamentals of Digital Circuits, combinational and sequential circuit.
OBJECTIVES
i. To study various number systems and to simplify the mathematical expressions
using Boolean functions – simple problems.

ii. To study implementation of combinational circuits
iii. To study the design of various synchronous and asynchronous circuits.
iv. To expose the students to
various memory devices.
