Prerequisite: Random    Signals & Noise.

Source Coding - Quantization techniques: uniform, companding, Lloyd-Max, VQ, high-resolution.Waveform coding: PCM, DPCM, delta modulation, adaptive PCM and DPCM, sub-band and transform coding. Transmission errors effect.

Channel Modulation/De-Modulation - Base-band digital communication (PAM): performance in ideal channel, matched filter, power spectrum. Line-codes. Channel impairment: inter-symbol interference (ISI). Nyquist’s criterion. Detection in the presence of ISI: maximum-likelihood sequence estimation, equalization (linear, zero-forcing, decision-feedback, adaptive, in the transmitter). Echo cancellation.
