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.
v. To introduce digital simulation techniques for development of application
oriented logic circuit.
