Module: Electrical measurements
The course aims to provide to the students the knowledge to design and build an automatic measurement chain for both traditional industry applications and modern smart solutions linked to the industry 4.0; it also intends to provide knowledge on both hardware and software solutions for the remote control of automatic measurement instruments, deepening the methodologies for processing digital measurement signals.


Module: Smart metering
The course deals with measurement science and its methodological and practical aspects. In particular it gives to the students information necessary for the correct interpretation of measurement results and for the knowledge of the behavior of a generic measurement chain.

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

Module: Electrical measurements
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 related to the design and realization of automatic measurement systems and the development of algorithm for signal processing.
The first one is focused on the discussion of the experimental project carried out during the course. The aim is to verify the real comprehension of the theoretical and practical aspect of both design and development of an automatic measurement system.
The second one is focused on the architectures of the automatic measurement systems, with the aim of highlighting the student's capability to make design choices on these arguments.
The last one is focused on the data communications interfaces, with the aim of highlighting the student's capability of describing it and make design choices depending on the application field.
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.
