The course “Automatic Measurement Systems” is designed to provide first year students of the “Laurea Magistrale” Degree in Electronic Engineering (Bachelor graduated students) with a deeper understanding of measurement area, with specific attention to advanced measurement technologies, methodologies and measurement signals processing concerning electrical quantities.
The Course aims at providing comprehensive knowledge of hardware and software useful for designing and using automatic measurement systems for industrial applications.
In details, the aims can be presented by the following five descriptors:
- Knowledge and understanding

Deep knowledge and understanding of theoretical and applicative topics in the field of industrial and automatic measurement systems. Knowledge of devices and techniques to design and implement an automatic measurement system.
- Applying knowledge and understanding
Ability to design and manage complex automatic measurement systems, by choosing devices that are most suitable both from a technical and economical point of view. Ability to integrate advanced measurement techniques with industrial level devices.
- Making informed judgements and choices:
Ability to evaluate results, select relevant information and suitable approximations to realize measurement systems. The student must test her/his capability to perform design choices and justify them.
-Communication skills
Capability to communicate technical information both orally and in writing. Ability to present and justify design choices. Ability to discuss problems and solutions with specialists and non-specialists. Anility to be either synthetic or accurate depending on the context.
-Continuous learning skills

Capability of continuous learning, through the proper interpretation of scientific and technical literature, manuals of manufacturers and technical standards.


The prerequisites are those indicated in the regulations of the "Laurea Magistrale in Ingegenria Elettronica" for admission to the first year.
Basic knowledge of electronics and conventional instrumentation for electrical quantities
Knowledge of the fundamental measuring methods and uncertainty evaluation and propagation.

Laboratory experience on data acquisition and elaboration with modular devices and general purpose devices.
Digital filters implementation.
Programs and prototypes for synchronized measurements.
Laboratory experience, scheduled to be faced also by students grouped by 2 to 3.

Ph.D students' and/or industry people's lectures.

Teaching Methods

The course is composed of 40 hours of theory lessons and 20 hours of practice, for a total of 60 hours. During the theory lessons, the teacher sets out the topics in the program; whereas during the practice sessions, students, working in small groups under the supervision of the teacher, learn how to design and implement using the techniques of virtual instrumentation their own solution to an assigned measurement project.

Verification of learning

Students have to develop a project (an example of Automatic Measurement System in Labview environment) on a topic covered during the course. A report on the laboratory activity is required. A discussion on the project and on theoretical issues is also required. As an example, the aim of the project developed in 2015-2016 was to design and implement an automatic measuring system concerning synchronized measurements for sinusoidal signals under different test conditions.
