Contenuti dell'insegnamento

The course will introduce the basics of electromagnetic signal propagation in an automotive environment where many different sources can influence and disturb its reliable transmission. Moreover, it will deal with the different aspects of electromagnetic compatibility of electronic circuits in complex environments. Filtering and shielding techniques for conducted and radiated disturbances will be discussed, along with conventional measurement methods and instrumentation.

Metodi didattici

The activity will be mainly based on presential theory lectures integrated with classroom exercises; group and CAD experiences will allow students to apply theoretical knowledge to practical problems.

Modalità verifica apprendimento

The exam is based on an oral test aimed to verify the student knowledge and understanding of basic EMC phenomena. The oral test will last about one hour and will cover all the aspects met during the course.
