Course Synopsis

1- Analyze the analog-to-digital conversion process with emphasis on Nyquist Sampling Criteria, line coding, pulse shaping and optimum detection functions. 2- Develop and compare the functional blocks of coding/modulation and demodulation/decoding for analog and digital communication systems. 3- Develop and compare the performance of binary, M-ary and spread spectrum digital communications in the presence of noise and interference. Design of linear systematic block coding and its error detection/correction capability is also discussed.

Course Learning Outcomes
