1. Course Objectives: Provide the fundamentals of analog and digital communication systems: representation of signals and systems in the time and frequency domains; analog modulation schemes; random processes; prediction and noise analysis using random processes; noise sensitivity and bandwidth requirements of modulation schemes; and a brief introduction to digital communications.

2. Course outline: • Fundamentals of signal and system analysis • Analog modulation techniques • Baseband communication systems in the absence of noise • A brief review of probability theory and stochastic processes • Noise effects in simple modulation systems
