EELE 445 - Telecommunications Systems
Spring 2015 (Last update: April 20)
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)
Notes:
- No Lab Final.
- HW 8 posted (last hwk!).
- Final will be takehome
