## Course handbook

### Description

This course starts from the frequency dependent behaviour of alternating current circuits and filters, and shows how Fourier series and Fourier Transform can be used to analyse a circuit's response. Subsequently, differential models and linear system interpretation of linear circuits are discussed, and the first ad second order transient behaviour of circuits is analysed using Laplace transforms. Some fundamental concepts of system theory such as transfer functions, impulse response and convolution are introduced. The course also covers the basic building blocks of a digital system including sampling, frequency domain analysis and elementary filters.
