Foundamentals of signals and trasmissions, prof. P. Boffi
Helded by prof. Pierpaolo Boffi.
School of Industrial and Information Engineering, Electronic Engineering
Short description: This module presents the fundamental theory on the transmission of analogue and digital signals. We consider the fundamentals of probability theory and random processes (including thermal and shot noise). We study time and frequency characteristics of deterministic and random signals, of linear time-invariant and time-variant filters which model a communication channel. Finally, we consider the transmission of analogue and digital signals in baseband and passband channels, with analogue and digital modulations, in amplitude, phase and frequency.

Foundamentals of telecommunications, prof. P. Boffi
Helded by prof. Pierpaolo Boffi.
School of Industrial and Information Engineering, Physics Engineering
Short description: The course is devoted to the description of technologies and architectures exploited in the telecommunications networks. The student will be able to understand how the network works, in particular the Internet network, and what are the basic elements and the principles of operation of a communication system.
The aim of the course is to show how the information has to be managed in order to be transported in the network, and the layer model together with the protocol operation. The characteristics of the physical interfaces and of the transmission media are also presented with the metrics used to evaluate the performance of a communications system. The course is also based on practical experimental demonstrations allowing the student to become familiar on the setup of a real communication link connected to the Internet network.

Electromagnetic waves and optics, prof. P. Martelli
Helded by prof. Paolo Martelli.
School of Industrial and Information Engineering, Telecommunications Engineering
Short description: The course, starting from the basic knowledge on electromagnetics, provides a deeper analysis of the theoretical aspects of electromagnetic waves propagation in free space (wave functions, polarization), in stratified media (for plane waves only) and in guiding structures (guided waves and optical fibers). The concept of radiation is then introduced. The course deals also with Fourier optics and the scalar theory of diffraction (apertures and gratings). Gaussian beams in free space are then discussed. Finally, interference and space and time coherence of light is introduced, together with some examples on optical resonators and interferometers.

Fondamenti di Reti e Internet, prof. A. Gatto
Helded by prof. Alberto Gatto.
School of Industrial and Information Engineering, Telecommunications Engineering
Short description: Il corso è dedicato alla descrizione delle architetture e delle tecnologie di comunicazione impiegate nella rete Internet. Lo studente avrà modo di comprendere come funziona la rete Internet e quali sono le scelte progettuali che hanno portato all’Internet del giorno d’oggi.
L’approccio didattico è basato su numerosi esempi pratici ed un utilizzo di strumenti software per supporto alle tematiche trattate e per consentire allo studente di acquisire dimestichezza sugli strumenti e sulle tecniche di dimensionamento e valutazione delle prestazioni di reti di telecomunicazioni.
Sono inizialmente illustrati i principi delle comunicazioni tra calcolatori e le caratteristiche di base dei protocolli adottati in Internet. In seguito, sono definiti alcuni concetti fondamentali alla base dei sistemi di comunicazione; l’obiettivo è quello di mostrare come l’informazione deve essere “trattata” per poter essere trasferita sull’Internet e quali sono le metriche usate per valutare le prestazioni di un sistema trasmissivo e, di conseguenza, di una rete di telecomunicazioni.
Successivamente l’architettura protocollare della rete è illustrata con un approccio top-down partendo cioè dal livello applicativo (più visibile all’utente finale) e proseguendo con il livello di trasporto, il livello di rete per finire con le tecnologie alla base delle reti locali.
Il corso è composto da due moduli non separabili. La valutazione finale sarà congiunta sull’intero programma.

Photons and Bits: at the roots of the information age, prof. M. Martinelli
Helded by prof. Mario Martinelli.
Ph.D. School
Short description: The course provide detailed view of origin of the concepts of “photon” and “bit”, the fundamental ingredients of our information age. Both concepts have their roots in the thermodynamics of the nineteenth century and the course examines the emergence of these concepts in their historical and epistemological background.
