Objective
CSE-318 course familiarizes the students with the principles of
communication systems and their applications in telephone, radio, and television
and computer communications. The course basically consists of two portions:
Analog and Digital Communications. In the analog communication portion various
techniques of modulation and demodulation of analog signals are discussed. Signalto-noise-ratio in (SNR) in analog AM and FM systems are also covered. The second
portion deals with digital transmission methods of analog signals. Discrete pulse and
carrier wave modulation schemes are also discussed. Bit error rate performance of
various digital communication systems is also included. Finally, a brief introduction is
given to the relatively new concepts in Digital Communication Technologies.
