- Linear systems and their properties. Causality, stability, time-invariance, invertibility
- Representation of systems by block diagrams, differential or difference equations
- Fourier series representation of periodic signals. Energy and power signals, distribution of energy over the spectrum of the signal. Discrete-time Fourier series and their use for the harmonic analysis of discrete signals
- Development of the Fourier transform as a limiting case of Fourier series of periodic signals with increasing period. Continuous and discrete-time Fourier transforms
- The use of Fourier transforms for the analysis of linear systems represented by block diagrams and differential equations
