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.
To be able to design analog and digital filters, starting from assigned technical specifications, to simulate them and implement most of them.
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.
Basic concepts of circuit theory, electronics, signal processing, automatic controls.
About 30 classroom hours and 30 lab hours. Due to the COVID-19 restrictions and due to a project for innovative teaching promoted by our university, the lab hours will be taken in the "flipped classroom" modality, under the guidance of the teacher and a tutor. The students will be provided with a toolkit for having lab experiences at home.

Regular (see the official calendar)
Oral: two discussions starting from two questions (one chosen by the student and one asked by the examiner) concerned with the topics treated during the lessons and to the design techniques applied during lab activities.
The learning results are assessed individually either
through the lab activities (max. 20 marks) and an oral exam (max. 10 marks)
through an oral exam (max. 30 marks)
