On successful completion of this subject the student will be able to:
1. Explain the mathematical basis for the frequency content of a signal with particular reference to the Fourier series and the Fourier transform.
2. Explain the mathematical basis of the frequency response of a linear, time-invariant system, analog or discrete-time.
3. Derive mathematical models for and analyse the response of linear, time-invariant systems, analog or discrete-time.
4. Effectively solve linear, constant coefficient ordinary differential and difference equations.
5. Effectively employ MATLAB in the analysis of signals and systems.
The topics outlined in the content will be complemented with examples. Computer-based simulations and experiments will complement the learning.
