• Fourier series, response to complex exponentials, frequency-selective filters LO1
• Fourier transform and its properties LO2
• Sampling and the sampling theorem LO2
• Laplace transform, region of convergence, LTI analysis LO2, LO4
• Linear feedback systems and second-order systems LO4

Learning outcomes

1. Analyse periodic signals with Fourier series
2. Analyse continuous-time signals and systems with Fourier and Laplace transforms
3. Analyse discrete-time signals and systems with the DTFT and z-transform
4. Find impulse, step and frequency responses, the response to any input, and feedback stability
