Aim
Electrical measurements relates to almost all professional areas where a person with a M.Sc. in Engineering will be active. It may, e.g., be detailed studies on signals from nerve cells in the brain, light detection in optical fibers or manufacturing supervision in process plants. The development of new measurement methods and transducers occurs at an increasing rate, where especially the development in the area of microsystem technology plays a major role. The course gives a deeper understanding of the measurement methods that have been used and will be used in other courses and in the professional life.

Knowledge and understanding
For a passing grade the student must

have knowledge in different measurement methods and how they are designed to measure voltage, current, impedance, time, frequency and frequency spectra.
have insight in limitations of measurements methods as well as influence of noise to avoid measurement errors.

Skills and abilities
For a passing grade the student must

be able to select a suitable measurement method and instrument for a given task and perform measurements.
have gained experience in experimental work.
be able to communicate results from lab work in writing.
be able to sort out and acquire information from a comprehensive material, e.g. a text book or lab exercise material, with limited reading instructions.

Judgement and approach
For a passing grade the student must

have realised the importance of critical examination of measurement results to minimise measurement errors and misinterpretations.

Contents
Fundamental concepts like loading of the measurement objects, influence of noise, uncertainty in the results and calibration. Analog and digital oscilloscopes, probes and their limitations, A/D and D/A conversion, digital multimeter, measurement of time and frequency with universal counter, measurement of frequency spectra with spectrum- and FFT-analyser (FFT Fast Fourier Transform). Design of measurement systems.
