Complex Measurement Systems

The student is acquainted with the general principles of complex measuring systems and the measurability of phenomena (introduction to complex measuring systems, limitations in measuring electrical and non-electrical quantities, measurability of parameters in sensory measurement, measuring scales, mathematical modelling, uncertainty of directly and indirectly measured quantities). She/he learns about the SI system of units and the basics of quantum metrology of electrical quantities. T

he content includes signal adjustment and noise reduction in electronic measuring systems (amplification, bridge binding, filtering,…) and floating measurements and protection (methods of performing floating measurements as a function of the measured signal, methods of performing protections, demonstrations of good protection execution practices, safety).

The student deepens her/his knowledge of measurement accuracy, measurement uncertainty and processing of results (basics of measurement accuracy, traceability, sources of uncertainty, processing and display of measurement results, measurement uncertainty in measuring dynamic phenomena). Measurements by field (medicine, electrical safety, environment, energy, …) are presented. 

The objective of the course Complex measurement system is to broaden knowledge about complex measurement systems and measurability of phenomena from different scientific areas. The student learns about measurement scales outside SI, mathematical modelling, and calculations of directly and indirectly measured quantities.

Within the course, basics of quantum metrology are given with associated current and future research topics.  In scope of the course student gets knowledge how to define requirements for data adjustment of signals (frequency, amplitude, power, …) and methods for optimal guarding of measurement systems, basic and advanced parameters of floating measurements. The course contains information about modern definitions of measurement uncertainty in static and dynamic measurements, data processing and presentation. Related to measurements, some signal processing techniques, e.g. correlations, auto correlations, are discussed and associated instrumentation presented. Acquired knowledge relates to classical measurement areas, as well as introduces soft or sensory metrology principles.

It also introduces interdisciplinary principles in the area of human perception in areas outside pure physical metrology, such as medicine, product and service design, psycho- sociology and similar.  

In scope of the lectures, the theoretical background on particular subjects related to complex measurement systems together with presentation of simple practical examples is given. A complete study material is available to the students.

Practical work is being performed in the laboratory environment and seminar, and is accomplished in steps acquainting students with the problem and complex measurement system. Each student individually prepares a seminar on complex measuring systems, typically outside of well-established measurement areas.

All the students have to present their work in the form of a seminar in order to practice presentation techniques.
