Digital Signal Processing

At the end of this course, the students should be able to: 1. explain the Fourier transform and its application in networks; 2. synthesize analogue and digital filters from network function; and 3. explain basic image processing concepts.

Discrete signals and Z-transform, digital Fourier transform, fast Fourier transform. The approximation problem in network theory. Synthesis of low-pass filters. Spectral transforms and their application in synthesis of high-pass and band-pass filters. Digital filtering, digital transfer function aliasing, one-dimensional recursive and non-recursive filters; computer techniques in filter synthesis, realisation of filters in hardware and software. Basic image processing concepts.
