Undergraduate - UnitECE2011 - Signal processing

Refer to the specific census and withdrawal dates for the semester(s) in which this unit is offered, or view unit timetables.

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.

Outcomes

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.

Assessment

Laboratory and assignment work: 30%
Examinations (3 hours): 70%
Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.
