MATLAB FOR ELECTRONICS
Learning outcomes of the course unit
The course aims to provide students with the knowledge of the main features of the MATLAB software in order to use it as a support tool to the electronics design. The student will learn how to apply the acquired knowledge to simple analysis and data processing problems by solving them through MATLAB and how to implement and verify algorithms in the MATLAB environment. Moreover, she/he will learn how to use MATLAB and SIMULINK in typical applications of electronics, electrical engineering and signal processing.
In particular, the student will learn 1. to work in Matlab environment, knowing the data types available and how to operate them, 2. to analyze and process the data for the preliminary study of algorithms and systems, also using specific toolbox. 3. How to resolve equations with MATLAB/Simulink 4. To design and to simulate a system using MATLAB/Simulink. 5. Flow Chart and Finite State Machine design with StateFlow. 6. to automatically generate C or VHDL code for Microcontrollers or FPGAs.
Finally, she/he will learn how to communicate and document the choices made through a well written and documented code.
Basics concepts about electrical circuits, electronics, signal theory and programming taught in previous courses.

24 lessons of 2 hours each.
The topics covered will be illustrated through slides and exercises.
Lessons will be held in streaming mode on Teams platform. Each lesson will also be recorded and the video will be made available on Elly platform for possible asynchronous consultation. The slides used and the exercises texts and solutions will also be published on the same platform.
Assessment methods and criteria
Practical test. The exercise could be:
- the elaboration of some data that will be provided by the teacher: the data will be imported with one of the techniques presented in the lesson, and then analysed and processed according to a particular algorithm provided in the examination text and finally plotted.
- Setting, analyzing, and simulating a electrical/electronic/signal processing system, with MATLAB and/or SIMULINK.
The test is evaluated on scale 0-32. The honors are reserved to a score of more than 30.
If, due to the persistence of the health emergency, it is necessary to organize exams in remote mode, the practical test will be carried out via Teams.
