TITLE Digital Signal Processing

 
LEVEL 02 - Years 2, 3 in Modular Undergraduate Course

 
ECTS CREDITS 5

 
DEPARTMENT Communications and Computer Engineering

 
DESCRIPTION This study-unit is about discrete time signals and systems. It first characterises discrete time signals and systems and then introduces several techniques to analyse these. The unit will then show, using digital filters as an example, how to apply these techniques to design discrete time systems that operate on signals in some pre-determined fashion.

The topics covered in this study-unit include the following:

- Discrete time signals and discrete linear time invariant systems
    o Impulse Response
    o Convolution Sum
    o Analysis of linear time-invariant systems in the z-domain
    o Poles and Zeros
    o Causality and stability

- Discrete Fourier Transform
    o Frequency domain sampling
    o Properties of the DFT
    o Circular convolution
    o Fast Fourier Transform
    o DFT for long data sequences

- Design of digital filters
    o Various Designs for linear phase FIR filters
    o Design of IIR filters from analogue filters
    o Direct design of digital IIR filters
    o Use of filter design software and filter tables

- Realisation of discrete time systems

Study-unit Aims

By the end of this study-unit the student should be able to analyse and design digital signal processing systems.

Learning Outcomes

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to analyse discrete time signals and systems both in the time and frequency domains using both mathematical techniques and also using simulation software.

2. Skills:

By the end of the study-unit the student will be able to design digital signal processing systems by filtering specific signals using both mathematical techniques and appropriate software.
