Objectives
The course provides general knowledge of an electronic
system as a system for information processing. In particular, starting from
basic concepts related to linear systems, the course aims to provide
mathematical tools for signal analysis and basic knowledge of analog and
digital electronics starting from basic components to get to electronics
circuits and finally to more complex electronic systems, focusing on the
application limits due to bandwidth, power and noise for analog and digital
circuits.
Expected learning outcomes: Students will be able to
analyze analog and digital electronic circuits and to design simple electronic
systems.
Learning outcomes
The course is aimed to provide the fundamentals of an electronic system able to process information. In particular, from the basic concepts of linear systems, the course provides the mathematical tools to analyse the signals and the basic knowledge of analog and digital electronics from the fundamental components to electronic systems including the most complex ones. At the end of the course it is expected that a students will have learned the links of frequency bands, power consumptions and noise in analog circuits and digital networks for space and satellite applications in transport, energy and communication infrastructures
Prerequisites
Fundamentals of electrical circuits, electrostatics and electromagnetism from the courses of Physics of Laurea degree.

Frequency
Strongly suggested for a better understanding and grasp of the course topics.
Exam mode
The exam consists in both mandatory written and an optional oral test. Th written text consists in a numerical test of a bout two hours related to the design of simple basic electronic systems. Homework assignments are given and evaluated as 20% of the final grade. The oral test is on the theoretical concepts of the course and can contribute to a maximum of 10 % of the final evaluation.
Example exam questions
Simple Bipolar or MOSFET transistor circuit amplifiers or by using operational amplifiers.
