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.

UNIT I - BOOLEAN ALGEBRA AND COMBINATIONAL CIRCUITS 9+3
Boolean algebra: De-Morgan’s theorem, switching functions and simplification using
K-maps & Quine McCluskey method, Design of adder, subtractor, comparators, code
