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.
