The course illustrates the basic principles of the measuring and of the electronic measuring techniques that are routinely applied into the modern electronic measurement instruments. The theme of measurements management is studied together with the traceability of the measurements to the international standards. The course, by means of the laboratory activity, introduces the student to the use of the main electronic measuring instruments.

Outline
Introduction to the measuring, repeated measurements and measurements variability sources, the measurement uncertainty and its evaluation.
Measuring by comparison methods, methods of nulling, potentiometer-based methods. The Weatstone bridge and its applications. Alternate current bridges.
Analog indicators: moving-magnet, moving-coil, and moving-iron devices. Amperometers and voltmeters.
Introduction to the SI organization. Measurement traceability and metrology institutes. The certification of the measurements.
The sensor as the measurement signal generator. The measuring chain and the electronic blocks for the processing of the measuring signal.
D/A and A/D conversion. Techniques for A/D and D/A devices. The oscilloscope.
