Electrical Engineering BA (B), Metrology, 7.5 credits

Aim

The course aims to provide students with knowledge about basic concepts and understanding of modern electrical measurement techniques. The measuring system being studied consists of the transformation from arbitrary physical quantities into electrical signals, analogue amplifiers and filters, the conversion to digital signals with subsequent signal manipulation to improve the signal to noise ratio.

Course objectives

After the course the student should be able to:
• develop a basic measurement system after specified signal to noise ratio, sensors, accuracy and dynamic behavior,
• apply different methods to improve signal to noise ratio in a measurement system,
• explain the phenomenon of channel leakage in DFT-analysis and of windowing,
• explain different factors affecting measurement uncertainty,
• explain principles for how noise is transfered and suppressed in measurement systems,
• explain basic princibles for measurement of non-electrical measurands,
• explain principles and limits when time continuous signals are sampled,
• explain principles and limits when time continuous signals are reconstructed,
• explain principles for conversion between analog and digital signals,
• explain principles for time continious and time discret filters.

Content

The course covers:
Sensors, amplifiers, sampling and reconstruction of time-continous signals, conversion between analogue and digital signals, frequency analysis, averaging, correlations, signal manipulation, measurement uncertainty, noise in electrical measurement systems, filters, dynamic properties of measurement systems, electrical instruments, LabView and computer based measurement systems.
