Integrated course unit module: WIRED AND WIRELESS INTERCONNECTIONS

Learning objectives

This module aims to provide the basic knowledge and skills to analyze and manage the coexistence, in the same ecosystem, of electronic devices considering electromagnetic compatibility issues. The guidelines to be followed to have a design approach that takes into account EMC issues will also be provided.

At the end of the course the student is expected to know: i) the fundamentals of the Electromagnetic Compatibility, with specific applications in the automotive framework; ii) the measurement techniques and the measurement instrumentation needed for the different measurement set-ups; iii) the approaches used to limit the emissions and increase the immunity of electronic equipment. He will also know the fundamentals for realizing designs of equipment and electronic circuits meeting EMC specifications.


Basic knowledge of electronics and electromagnetics.

Course unit content

General introduction to the Electromagnetic Compatibility (EMC).

Teaching methods

The teaching of this module (3 credits) mainly includes delivered lectures, with theory and examples related to applications in the automotive framework.

The lectures material (slides) is provided before the corresponding class takes place.

Periodically, during the course, some lectures are carried out interactively (or in flip-mode), presenting questions to which students are required to give reasoned answers.

Assessment methods and criteria

The exam consists of an oral interview (of around 30 minutes) on the main topics of the course.

During the exam, the student can use a map with the main formulas of the course.
