Course Curriculum CFU Length(h)


The course Data Acquisition Technologies is designed to provide second year students of the Laurea Magistrale Degree in Electronic Engineering with a deeper understanding of technologies for measurement, with particular attention to acquisition, synchronization and remote instrument control technologies, and to complex measurement system design.
The Course aims at providing a high-level knowledge of hardware and protocols for designing and running acquisition and measurement systems of industrial level.
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 technology for measurements. Knowledge of devices, hardware and protocols to design and implement an up-to-date and maintainable measurement system.
- Applying knowledge and understanding
Ability to design, implement and manage measurement systems, by choosing devices that are most suitable both from a technical and economical point of view. Ability to integrate instruments and devices of industrial level.
- 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. Ability to be either concise 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 advanced measuring methods and uncertainty evaluation and propagation.

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 use different technologies, to design and implement acquisition and measurement systems for specific applications.

Verification of learning

The examinations are carried out by oral exam aimed at discussing course topics and linked laboratory experiences are discussed and at verifying the preparation of the student in other topics included in the course.
The final mark to pass the exam ranges from 18/30 to 30/30. The evaluation rewards students autonomy and capability to rethink the theoretical lessons in applications, communicate clearly relevant characteristics and highlight possible issues.
In this regard, the questions of the oral are organized to highlight the following aspects:
- Acquired knowledge of theoretical topics
- The applied knowledge and understanding, with particular attention to practical cases
- dalle esigenze di un sistema reale di acquisizione e misura. The capacity to choose among different technologies depending on needs and requirements of a real acquisition and measurement system.
