The teaching is organized as follows:

Learning objectives

Starting from introduction to electrical network analysis, the course aims to provide students with the fundamental notions of analog and digital electronics useful for understanding how sensors and medical devices work. At the end of the course, the student will be able to understand the operation of traditional analog and digital circuit diagrams, to know and measure the main static and dynamic performance parameters and to be able to use the basic elements of main specification languages and automatic design and simulation tools. The students will also have to demonstrate that they have the necessary skills to continue their studies independently in the field of analog and digital electronics.

Prerequisites and basic notions

In order to be successful in acquiring the course contents, at the beginning the student shall be very confident with the following concepts:
- Mathematics: basic notions; derivatives and integrals; differential equations.
- Physics: basics of mechanics and electricity.

Program

The course is composed by two 6 CFU modules
- module 1: Electric circuits
- module 2: Electronics

Didactic methods

Students are strongly advised to attend lectures, which include explaining the theory and carrying out exercises on the analysis of simple electrical circuits and electronic circuits. For the study, students are invited to use the course materials provided by the lecturers and to solve the exercises they propose. Simulation activities of electrical and electronic circuits are also organized by means of LTSPICE.

Learning assessment procedures

The assessment of preparation is carried out through two written tests, one for the ELECTRICAL CIRCUITS section of the course, the other for the ELECTRONICS section. The duration of each test is 2 hours.
ELECTRICAL CIRCUITS
Students are proposed a written test consisting of two open questions on the content of the course (with the aim of verifying the level of theoretical knowledge) and an exercise about the analysis of an electrical circuit (with the aim of verifying the problem solving skills). The duration of the written test is 2 hours. A maximum score of 10 is assigned to each question, while a maximum score of 11 is assigned to the solution of the electrical circuit. If the written test is evaluated at least 15/30, with a score of at least 4 on the exercise, the assessment can be employed for the final evaluation. If the test is graded at least 18/30 then the test for this section of the course is passed.
ELECTRONICS
The (written) test for this section of the course is made up of 5 questions, of which 2 are open questions or multiple-choice questions, and 3 in the form of an exercise on the analysis or synthesis of a digital circuit / system. The maximum score attributed to each question is indicated in the text. If the test for this section of the course is graded at least 15/30, then the score can be considered for the final score. If the test is graded at least 18/30 then the test for this section of the course is passed.

Evaluation criteria

To pass the exam, the score assigned to each test must be at least 15/30, with a score of at least 4/30 in the exercise on electrical circuits. In addition, the score obtained in each test is valid only until the start of the lectures of the related part of the course in the following academic year.

Criteria for the composition of the final grade

The final mark is obtained as the arithmetic average of the scores assigned to the two modules, rounded to the nearest integer. The exam is passed if this average is at least equal to 18/30.
