 Obiettivi dell'insegnamento
 This course focuses on the analysis of signals (sound, acoustic pressure, voltage, images, etc.) and the systems that act on them (acoustic resonators and environments, circuits, mechanical devices, etc.). We concentrate on the Fourier Transform and Linear-Time Invariant Systems, providing the fundamental mathematical tools for sampling, manipulating, preserving, and interpreting information signals. This first module of the course is dedicated to analog signals and systems.

 Risultati di apprendimento attesi
 Expected learning outcomes   Knowledge: - An in-depth understanding of the fundamental mathematical tools for the representation and decomposition of analog signals - An in-depth understanding of how analog systems generate analog signals and/or interact with them.   Skills: - Ability to derive suitable models of linear-time invariant analog systems, and appropriate representations of the related signals.
