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.

Assessment: Examinations (3 hours): 70% + Laboratory and assignment work: 30%. Student must achieve a mark of 45% in each component to achieve an overall pass grade.

Contact Hours: 3 hours/week lectures and 3 hours/week laboratory and practice classes and 6 hours of private study per week.
