ECE2011 - Signal processing

6 points, SCA Band 2, 0.125 EFTSL

Undergraduate Faculty of Engineering

Leader(s): Jingxin Zhang, Y C Kuang (M'sia)

Offered

Clayton First semester 2009 (Day)
Sunway First semester 2009 (Day)

Synopsis

This unit will cover continuous-time and discrete-time signals, including sampling, aliasing, and the sampling theorem. Complex exponentials, and their representation as phasors, lead to periodic waveforms, Fourier series and the signal frequency spectrum. Modification of spectra will be described, using FIR filters, discrete-time systems, unit-sample response, discrete convolution, frequency response of FIR filters, z-transforms, IIR filters, linear time-invariant systems, convolution integrals, continuous-time Fourier transform, windowing, DFT, FFT, time-frequency spectrum analysis, spectrogram. Connecting frequency response and time response completes the unit.

Objectives

To understand signals and how they are analysed and modified by systems. To understand the strengths and weakness of sampled and digitised representations of signals, including images, in both time and frequency domains. To experience the strength of mathematics in describing these processes.
