CET731 Multirate Digital Signal Processing

Course Provider

School of Electrical and Electronic Engineering (EEE)



Academic Unit



The objective of this course is to introduce multi-rate digital signal processing, which has been widely used in many practical applications such  as in image, audio and communications. The objective includes imparting  special attention for integration of sampling and filtering to achieve the  needed operations.

This course is part of:

- Graduate Certificate in Signal and Media Processing
- FlexiMasters in Signal and Media Processing

Advanced concepts and implementation of sampling process and filtering, and spectrum analysis are introduced. Techniques combining these  concepts and operations are discussed. Optimization in terms of accuracy performance and computational complexity is also conducted.

Various types of digital filters and their properties are discussed. Filter specifications for a particular application are explained. The methods of  generating filter coefficients are also provided. For spectrum analysis, discrete Fourier transform is studied. Its computational complexity and  limitations are to be discussed. For random signals, non-parametric approaches and eigen-analysis-based algorithms for power spectrum  estimation will be covered.

For engineers who wish to upgrade their technical knowledge and skills  in the area of digital signal processing, which can be used in the Infocomm industry to aid in resampling and in filterbank based  decomposition of any kind of signal.
