AIMS AND CONTENT

LEARNING OUTCOMES

The course provides the basic knowledge needed for the analysis and design of simple electronic circuits, both analog and digital, aimed at performing physics measurements. Particular attention is paid to the use of laboratory instruments and the use of data acquisition techniques.

AIMS AND LEARNING OUTCOMES

By the end of the course, students will have developed the ability to:
- use the main tools adopted for the analysis of electronic circuits, having understood their operating principles;
- design and build analog circuits aimed at processing DC and AC signals;
- design digital circuits starting from the desired specifications or from the description of the algorithmic behavior to be implemented;
- interfacing microcontrollers and microprocessor systems with the aforementioned instruments and circuits;
- understand the project behind an experiment performing a physics measurement and relying heavily on electronic circuits, developing the critical thought to modify the project itself;
- communicate, using the correct technical / scientific language, the specifications of the circuits built in practice and the results of the experiments performed.

EXAM DESCRIPTION

The exam consists of two parts:

- a practical laboratory test aimed at determining the student's ability to design, build and characterize a circuit, analog or digital, similarly to what seen in the guided exercises carried out during the year

- an oral test in which their knowledge and understanding of the theoretical topics covered during the course are verified

ASSESSMENT METHODS

The practical test evaluates the ability to design analog and digital circuits starting from the required specifications.
If the construction of a prototype is required, the quality of its technical characterization is evaluated.
In the oral discussion, circuit design skills are further verified, and the theoretical understanding of the key concepts presented in the course is also evaluated.
