Electronic Measurement Systems
FEKT-BEMSAcad. year: 2015/2016
The course deals with the modern approach to the implementation of measurement - using and working with electronic measuring systems. It is focused on technological means of automation - standard interfaces, eliminating the measurement uncertainty, using the DSP in measurement. Deals also with selection of components used in measuring instruments.

10th Communication measuring instruments to a PC (RS232, USB)
11th Computer technology in the automation of measurement - Digital signal processors, generation, general properties. DSP TMS320C6748, obvody ARM+DSP (OMAP138 TI)
12th Analog devices in measuring systems - criteria for selection switches analog signals, amplifiers (modulation-device with galv. Separation), rectifiers for measuring technology, samplers, A/D and D/A converters
The aim is to teach students to work with measurement systems and propose them to the hardware level, an overview of the standards in this area. Student is able to determine the measurement uncertainty in the system, select a suitable design and build the system. He knows the way to describe the system to forward the requirements for software design.
