3. To teach the pulse modulation techniques.

Course Description

Introduction, spectral analysis, transmission through linear systems. Linear modulation techniques: Carrier amplitude (AM), double sideband (DSB), single sideband (SSB) and vestigial sideband (VSB)/demodulation. Exponential modulation techniques: Frequency and phase (FM and PM) modulation/demodulation. Frequency division multiplexing (FDM). Stereo transmission. Superheterodyne receivers. Introduction to random processes, noise modeling and AWGN channel. Noise analysis in linear and exponential modulation systems. Sampling, pulse amplitude, width and position modulations (PAM, PWM, PPM). Quantization, pulse code modulation (PCM), delta modulation, differential PCM. Digital PAM, PWM, PPM. Time division multiplexing (TDM).
