Norgia, Ottoboni, Pesatori, Svelto, Measurements from fundamentals to instrumentation, Published by Esculapio, Edition 2022 Lecture notes will be made available on the Google Classroom (access code: ephbkkb).

Attendance is not mandatory. However, student participation is strongly recommended for the acquisition of the skills outlined in the objectives of the course.

The assessment of the acquired skills is based on an oral exam structured on three open oral questions. Its objective is to assess the level of understanding of the topics covered in the course, and the student's ability to apply the acquired skills to solve problems in the field of electrotechnics and electrical measurements. One of the questions is focused on a practical experiment carried out during the course. The aim is to verify the real comprehension of the theoretical and practical aspect of a measurement procedure. The final exam outcome is obtained averaging the marks given on the single questions. A sufficient mark to each question is required to overcome the exam.

Lectures, numerical exercises involving the students, and experimental activities. The students will be asked to cooperate on the development of technical reports regarding the experimental activities carried out in the laboratory.
