Objectives

The class aims at providing the student with the elementary notions in the field of modern Electronics. In a top-down approach, a quantitative overview ranging from integrated digital systems, to electronic circuits and electron devices, both in the the fields of digital and analog signal elaboration, is presented.

Acquired skills

- Knowledge of the main electron devices.
- Analysis and design of analog circuits.
- Analysis and design of simple digital circuits and logic networks.
- Understand and analyse interconnections among electronic.
- Knowledge of the main circuit schemes for A/D and D/A conversion.
