Module description
Measurement is an essential part of the scientific process. Instrumentation is the technology of measurement. In this course, students are taught the fundamental principles of instrumentation, to design a measurement system which takes due regard of problems such as accuracy, time response and noise of the overall system and of its suitability for particular measurement.

Learning outcomes
After taking this module students should be able to:

Additional learning activities
Problem solving sessions.
Some group experimental work if time allows.
