SYLLABUS:

EE2255	DIGITAL LOGIC CIRCUITS	L T	P C
		3 1	0  4

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

Boolean algebra: De-Morgan’s theorem,  switching  functions and  simplification  using  K-maps & Quine McCluskey method, Design of adder, subtractor, comparators, code converters, encoders, decoders, multiplexers and demultiplexers.

UNIT II           SYNCHRONOUS SEQUENTIAL CIRCUITS          9

Flip flops - SR, D, JK and T. Analysis of synchronous sequential circuits; design of synchronous sequential circuits – Counters, state diagram; state reduction; state assignment.

UNIT III           ASYNCHRONOUS SEQUENCTIAL CIRCUIT       9

Analysis of asynchronous sequential machines, state assignment, asynchronous design problem.

UNIT IV          PROGRAMMABLE LOGIC DEVICES, MEMORY AND LOGIC FAMILIES        9
