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
