Signal processing

A.Y. 2020/2021
Overall hours
Learning objectives
The aim of the course is to teach the fundamental concepts of signal and system theory, focusing on continuous-time and discrete-time signals and systems (with specific reference to acoustic signals). The course focuses in particular on: signal and system representations in time- and frequency-domain, signal processing (filtering), and analog/digital signal conversions.
Expected learning outcomes
At the end of the course, the student shall be able to: represent signals and systems both in the time domain and in the frequency domain; design continuous-time and discrete-time filters; correctly design an analog-to-digital signal conversion.
Course syllabus and organization

Single session

Lesson period
First semester
Course syllabus
The class is dedicated to the fundamentals of signal theory and the basic concepts of analog and digital signal processing.
The main topics are:
- Elements of complex mathematics
- Signals and systems
- Frequency analysis: Fourier series and Fourier transform.
- Filtering of analog signals.
- Analog/digital conversion: sampling, quantization.
- Time-discrete Signals.
- Frequency analysis: of discrete signals: DTFT, DFT.
- The Z-transform.
- Digital filters.
Prerequisites for admission
