Analog and Digital Communication Systems
Credits: 3 + 0.5
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. Pre-Requisites or background study required Calculus, Linear Algebra, Signal & Systems Consulting Hours Instructor : Monday-Thursday 03:15-04:15 pm Text book • Modern Digital and Analog Communication Systems (3rd Edition) by B.P.
