Course aims:

The course is centered around the problems that rise during measurement operations, data processing and measurement data interpretations
The use of these devices is of great interest. Multiple measurement devices, both for analog and digital signals will be studie
This course will treat specific examples of measuring devices and specific systems which are integrated in advanced measuring system blocks
This course focuses on statistical methods of processing data series and measurement data
The maintenance work needed for these measurement devices is also studied

Course Entry Requirements:

1) Electronics and telecommunications measurements 2) Electronic measurement systems and tools 3)Transmissions and data encodings
