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.

After taking this module students should be able to:

- understand the basic characteristics of signals.
- understand the origins of noise.
- understand the operation and limitations of some transducers.
- appreciate the limitations of amplifier circuits.
- understand the operation of simple filters and differentiate between passive and active filters.
- understand some simple signal processing techniques, such as signal averaging and phase sensitive detection.
- understand the basic principles of computer interfacing.
- appreciate the problems associated with converting analogue to digital systems.
