This note teaches the
basic signal-processing principles necessary to understand many modern high-tech
systems, with a particular view on audio-visual data compression techniques.
Topics covered includes: Signals and systems, Phasors, Fourier transform,
Discrete sequences and spectra, Discrete Fourier transform, Spectral estimation,
Finite and infinite impulse-response filters, Random sequences and noise,
Correlation coding, Lossy versus lossless compression, Quantization, image and
audio coding standards.
