Subject fundamentals
This mandatory course is part of the three year Bachelor’s degree on Cinema and Media Engineering. It is offered during the 2nd semester of the 2nd year. It provides fundamental notions of electrical and electronic circuits, which are needed in ordered to understand the structure and the operation of the main categories of electronic circuits that are used in digital communications.
Electrical circuit theory is introduced by providing methods to understand and analyze electrical networks including both linear and non-linear components.
Fundamental notions of electronics are explained using a system-oriented approach. After identifying the main functional modules that are part of an electronic system, and after studying their behaviors and interfacing mechanisms, an in-depth study is devoted to how digital technology is used for multi-media communications. Covered topics include fast and sophisticated digital signal processors; reliable transmission and high-resolution displays.
Expected learning outcomes
This course provides basic knowledge that will allow a student to understand the operation of electronic systems, identifying their main components, and evaluating their key characteristics. This knowledge will also allow the student to design simple analog and digital circuits.
Prerequisites / Assumed knowledge
Basic courses on physics, geometry and mathematics. In particular, the student is assumed to know differential equations, matrix computations, linear algebra (determinants, rank, and linear independence), and complex numbers.

Delivery modes
Discussion sessions will require the students to solve some simple analysis problems of electrical and electronic circuits, using the techniques covered during lessons.
Four laboratory sessions will be devoted to design, implementation and measurements for simple analogue designs (operational amplifiers) and digital designs (logic circuits).
