OVERVIEW

In the first semester, the course aims to provide students with the basics of the theory of continuous-time signals and systems with special focus on Fourier transforms, frequency-domain analysis, and linear time invariant (LTI) systems.

Sampling is introduced both ideally and in its real versions, along with quantization and analog-to-digital conversion through the pulse code modulation (PCM) technique. Digital transmission is dealt with through wideband pulse amplitude modulation (PAM). Time-division and frequency-division multiplexing are discussed.

The theory of random phenomena is presented in the second semester, which is composed of the three parts of probability, random variables and random processes. The problem of the band-pass transmission on noisy channels is therefore addressed, describing linear modulations, AM, DSB and SSB, and angular modulations, FM and PM.

 

AIMS AND CONTENT

LEARNING OUTCOMES

Basic principles of signals and linear systems. Spectral analysis of continuous signals; discrete signals; sampling and analogic to digital conversion. 
Random phenomena theory: probability, random variables, random processes. PAM, PCM, and analog modulations. Transmission techniques on noisy channels. 

AIMS AND LEARNING OUTCOMES

After the course, the student shall:

- know the theoretical bases of continuous-time signal processing and analysis;

- know and be able to use the continuous-time Fourier transform;

- be able to map from the plot of periodic and aperiodic signals to their mathematical formulations, in both the time and frequency domains;

- know linear time-invariant (LTI) systems, in terms of both impulse responses and their transfer functions, and be able to use them in the solution of problems;

- know under which conditions an ideal or real sampling process allows a signal to be reconstructed;

- know and be able to use the theory of stochastic processes;

- know and be able to use the theory of passband analog communications;

- know and be able to use the theory of baseband digital communications in the wideband case;

- know and be able to use the theories of frequency-division and time-division multiplexing.

EXAMS

EXAM DESCRIPTION

The exam consists of a written test and an oral test. The written test can also be dealt with by two small parts, relating to the program carried out in the first and second semester. Written tests consist of solving problems.
The marks of the written and oral tests are considered both for the determination of the final grade, according to a non-mathematical criterion that holds account of the overall evaluation of the candidate, also in continuity with the previous history of the course.

Students with learning disorders ("disturbi specifici di apprendimento", DSA) will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.

ASSESSMENT METHODS

The written exam will assess the student's capacity to solve problems on the course topics. The formal correctness, the capability to perform math calculations, the capability to apply formulas and concepts taught in class, the clarity of explanation, the legibility of the test will be evaluated.

The oral exam will assess the student's comprehension of the course topics. Formal correctness, understanding of the concepts, critical reasoning, clarity of explanation, and use of the appropriate lexicon will be evaluated.
