This course has two main objectives. The first is to present a sound theory of uncertainty, according to current accepted international standards and practices, introducing also several advanced tools. The second is to introduce a number of fundamental instruments that are part of a typical electronic laboratory, describing their principle of operation, important specifications, sources of uncertainty and applications.

In addition to lectures, the course consists of in-class exercise sessions, laboratory sessions and homework assignments.
Exercise sessions are aimed at analysing practical measurement situations involving different type of instruments.
Laboratory sessions are aimed at developing experimental skills, practicing with the laboratory instrumentation described in the lectures and introduce a number of applications. The laboratory sessions focus on the following topics: uncertainty, frequency measurements, frequency synthesis with phase-lock loops, spectrum analysers.
Homework assignments presenting exam-like problems are aimed at encouraging a gradual study of the subject (optional, with approximate biweekly frequency).

The exam consists in a written test followed by an oral examination.
The written test (2h30min) is composed of two problems (15 points each) in which students have to analyse or design a measurement set-up, evaluating uncertainties and discussing sources of errors. The written test is open books and students can use a scientific calculator. The minimum pass grade for the written test is 18/30. The oral examination (30-45 min) consists of two open questions about the operation of devices and instruments described in the course and their uncertainties: the student is expected to present the most significant aspects of the topic in a coherent and autonomous way. The grades of the two parts are averaged to yield the final grade.
Students can optionally and individually deliver either a presentation (with slides) on one of the laboratory sessions of their choice or discuss a research paper (no slides, but the student can use their own notes on the paper). These optional activities (20-30 min) can grant up to 4 points to be added to the final grade.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

The maximum grade without the optional part is 30. With the optional part, 30L is awarded for a total number of points greater than 32.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
