Language: Italian
The aim of the course is to provide an introduction to the ideas and methods of Fourier's analysis, the bull, the straight and the discrete case. Among the applications considered, particular emphasis will be placed on problems and techniques of signal analysis, such as the sampling theorem and the transformation of Gabor.
Teaching style: In presence
