PRINCIPLES OF COMMUNICATION ENGINEERING

L T P

4 - 3

RATIONALE:

The study of principles of communication systems leads to further specialized study of audio and video systems, line communication and microwave communication systems. Thus the diploma holder in electronics and communication engineering shall find employment in areas of R & D, Production, Servicing and Maintenance of various communication systems. The students should understand the advantages and limitations of various analog and digital modulation systems on a comparative scale and relate to them while studying practical communication systems.
