Introduction
The lab is part of course component.
The course consists of: Review of discrete-time signals and systems, the sampling theorem, and Fourier series/transforms. Sampling rate conversions. A/D and D/A conversions. Z-transform and LTI system analysis. Minimal, maximal and mixed phase systems. Discrete Fourier Transform and Fast Fourier Transform (FFT). Windowing effects. Finite Impulse Response (FIR) filter design (linear phase, windowing, frequency sampling, Remez). Infinite Impulse Response (IIR) filter design from analog prototypes. Frequency transformations. Structures for implementation: direct, cascade, lattice, lattice-ladder, parallel. Finite word length effects. Introduction to spectral analysis. Real time implementation.
Prerequisite: ELG 3125
