EELE 445  Telecommunications Systems
Course Description 

Introduction to analog and digital communication systems with lab. Topics include signals in communications; noise characterizations; bandwidth considerations; probability of error; analog and digital modulation; frequency domain analysis; matched filter applications. Experiments involve modulation, demodulation, A/Ds, sampling theory, and aliasing. (Syllabus)
