Teaching methods

Frontal lessons and practical sessions with pc and beamer. Practical sessions will face the analysis and design of simple electronic circuits, with the goal of providing students with the ability to analyze and design simple electronic circuits autonomously.

Assessment methods

The final examination is written. It consists in the anlysis and/or synthesis of an electronic circuit similar to those consodered during the practical sessions. It might include also some questions in order to verify the knowledge of theoretical subjects introduced during the course.
