Course detail

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.

Aims

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.
