For all other bteup syllabus 4th sem electronics eng 2022 you can visit BTEUP Syllabus 4th Sem Electronics Eng 2022. The detail syllabus for principles of communication engineering is as follows.

Rationale:

The study of principles of communication systems leads to further specialized study of audio and video systems, line communications and microwave communication systems. Thus the diploma-holder in Electronics and Communication Engineering shall find employment in areas of R and D, production, servicing and maintenance of various communication systems. The students should understand the advantage and limitations of various analog and digital modulation systems on a comparative a scale and relate to them while studying practical communication systems.

Learning Outcomes:
