EC 2252           COMMUNICATION  THEORY                                                                                               

AIM

To study the various analog communication fundamentals viz., Amplitude modulation and demodulation, angle modulation and demodulation. Noise performance of various receivers and information theory with source coding theorem are also dealt.

OBJECTIVES

  •  To provide various Amplitude modulation and demodulation systems.
  •  To provide various Angle modulation and demodulation systems.
  •  To provide some depth analysis in noise performance of various receiver.
  •  To study some basic information theory with some channel coding theorem.
