Study-Unit Description


TITLE Advanced Digital Signal Processing

LEVEL 05 - Postgraduate Modular Diploma or Degree Course


DEPARTMENT Communications and Computer Engineering

DESCRIPTION Study-Unit Content:

• Review of the sampling theorem: relation of analog frequency response and digital frequency response;
• Review of the Z-transform: time series and their z-transforms, relationships, and analysis on unit circle;
• Discrete Fourier Transform: Circular convolution, linear convolution using the DFT, time-frequency relationships, the FFT, the discrete cosine transform;
• Digital Filters: FIR and IIR designs from z-transforms;
• Power Spectrum Estimation: windows, window spectral leakage, narrowband and wideband spectrograms;
• Multirate signal processing: decimation and interpolation of the sample points, and their effect on bandwidth and time series; polyphase structures;
• Linear Prediction and Optimum Linear Filters;
• Time-frequency signal processing: wavelet transform;
• Sparse coding: optimisation function, orthogonal matching pursuit.

Study-Unit Aims:

The aim of this unit is to offer more advanced topics in digital signal processing to students who already have a basic knowledge of DSP.
