ELEMENTI DI ELETTRONICA

The main objectives of the course are:

- the ability to represent signals in the time and frequency domain;

- the knowledge of methods and theorems useful for the resolution of electrical networks;

- the ability to define the characteristics of linear time-invariant systems in the time and frequency domain;

- the capability to develop simple 'interactive objects', taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other physical outputs with an open-source physical computing platform based on a simple microcontroller board.
