| Educational objectives | Training goals - Understanding of Measurement Theory fundamentals - Understanding of architecture of basic electronic measurement and lab instrumentation (oscilloscopes) -Understanding of the main methods for measuring electric quantities - Understanding of methods for estimating and reducing measurement uncertainty, and of their usage in compliance verifications Skills -Capability of designing and realizing a system for measurement of electrical quantities -Capability of selecting and using electronic measurement instrumentation -Capability of evaluating measurement uncertainty in a given measurement - Capability of designing a compliance verification |
| Prerequisites | For a better understanding, skills related to courses of Calculus I/II, Physics B, Probability Theory, Circuit Theory, and Electronic should be already acquired |
| Teaching methods | Face to face lesson, lab activities |
| Other information | This Unit aim at providing knowledge and skills with respect to Measurement Theory, measurement of electric quantities, and modern measurement instrumentation. Lab activities are envisioned, to consolidate both knowledge and skills. |
| Learning verification modality | Written exam (2 hours), followed by an oral test (20-25 minutes) The 2-hour written test (10 multiple-choice questions, one open question, and one numerical exercise) aims at verifying the acquired knowledge and ability to connect different topics to solve practical problems. The optional oral test enables the student to show other aspects of the acquired knowledge during a 20-25 minutes discussion with the commission. |

Skills developed at the end of the module: - ability to choose and realize conditioning systems for electrical measurand quantities - ability to design and use data acquisition systems |
| Prerequisites | Knowledge related to the Analisi matematica I e II, Fisica B, Teoria dei Circuiti, and Elettronica modules are recommended. |
| Teaching methods | Classroom lectures, lab activities |
| Other information | None |
| Learning verification modality | The exam is comprised of a written test, an oral test, and the presentation of a project activity. The 2-hour written test (10 multiple-choice questions, one open question, and one numerical exercise) aims at verifying the acquired knowledge and ability to connect different topics to solve practical problems. The oral test enables the student to show other aspects of the acquired knowledge during a 20-25 minutes discussion with the commission. The project activity aims at developing and characterizing data acquisition systems. |
| Extended program | - Digital multimeters - Measurement of electrical quantities in the industrial environment - Digital oscilloscopes - universal counters - Spectrum analyzers Architecture of data acquisition systems Usage of lab instrumentation for electronic measurements: multimeters, oscilloscopes, voltage probes, function generators, spectrum analyzers. Procedures for the characterization of electronic components. Classroom lectures will be integrated with lab activities using measurement instrumentation, hardware and software systems for data acquisition and processing (e.g. Labview). Lab activities represent a fundamental part of the module. |
