OVERVIEW

This subject aims to provide basic elements for the design and synthesis of analog and digital filters. One half of the lectures is given in laboratory, where the students are driven to design, simulate, implement and test different kinds of filters, by using tools such as PSPICE, MATLAB and laboratory equipment.

AIMS AND CONTENT

LEARNING OUTCOMES

The goal of the course is to provide the basic notions for the design of analog (both passive and active) and digital filters tailored for processing sensor measurements in robotic applications. The topics are proposed to students through both theoretical lessons and practical activities such as the simulation and the hardware realization of filters.

AIMS AND LEARNING OUTCOMES

It is expected that at the end of this subject the student will be able to design analog and digital filters, starting from assigned technical specifications, and to simulate them. Moreover, he/she should be able to implement and test the kinds of filters physically realized and tested during the lectures. To this end, he/she has to learn the main peculiar features of each class of filters and the corresponding design techniques described during the classroom lectures. Given a specific filter design problem, the student has firstly to decide what class of filters can be (or has to be) used to solve it. Then he/she can start designing the filter, by using not only the techniques specific for filters, but also general concepts coming from other areas, such as signal processing and automatic controls, as illustrated during the lectures. This capacity of solving non-trivial problems is one of the main elements of the scientific cultural baggage of an engineer.

PREREQUISITES

Basic concepts of circuit theory, electronics, signal processing, automatic controls.

TEACHING METHODS

About 30 classroom hours and 30 lab hours.
