Electronics, Signal Theory, Electromagnetic fields, Electronic Measurements
The course provides the basic concepts for a correct use of measurement instrumentation adopted in testing, diagnostics and metrological characterization of components, devices and telecommunication systems.
Instrumentation and measurement methods mainly adopted in the field of TLC applications will be presented, analysed and used.
The course also includes several practical laboratory sessions.
1) Knowledge and understanding
The course describes methods and models in the field of measurement systems and apparata with a specific focus on TLC. Students must have basic knowledge related to electronics, electronic components, signal theory. They should know the main electronic architectures and signal acquisition systems operating both in time and frequency domains. They should be able to deal efficiently with practical applications and measurement issues with a specific skill to cope with the intrinsic limitation between theoretical models and practical cases.
2) Applying knowledge and understanding
At the end of the course, the student should be able to apply rigorously the basic and most important concepts related to metrology for a generic measurement process. Specifically, the student should be able to correctly use measurement instrumentations adopted in testing, diagnostics and characterization of components, devices and telecommunication systems.
3) Making judgements
Students will possess the ability to identify the operating modalities for correlating a theoretical concept or model with the most appropriate practical context. The course promotes the development of independent judgment suitable to appropriately choose the measurement technique as well as the critical ability to interpret the goodness of the results of the models/methods applied to the datasets under examination.
Through the methodologic tools provided in the course and, in particular, those addressed during the laboratory sessions, students will be able to communicate with an appropriate technical terminology so as to proficiently deal with all the issues related to measurements, data acquisition and processing, testing activity and results.
Additionally, thanks to the laboratory sessions, the students will have the opportunity to draft autonomously a technical report describing the practical and theoretical issues related to the discussed topics.
5) Learning skills
Students must acquire the critical ability to relate, with originality and autonomy, to the typical problems of measuring a quantity, characterizing a TLC signal and testing electronic devices and components. They will also be able to use instrumentation and measurement methods largely adopted in the field of TLC applications and they should be able to apply autonomously the knowledge and methods learned in view both of a possible PhD courses as well as of a professional carreer.
The course is highly characterised by a practical approach thus, in addition to traditional lessons, several practical laboratory sessions are carried out.
Oral and practical exam, including the production of a technical report describing the laboratory experiments.
