Brief description
Measurement is an essential part of the scientific process. Instrumentation is the technology of measurement. In this module, 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 its suitability for a particular measurement
Content
What is an electronic instrumentation system? A topdown approach to system design.
Types of signal encountered by instrumentation systems.
Important terms assocaited with instrumentation systems.
Comparison of digital and analogue instruments.
Noise in instrumentation systems and its characterisation.
Physical origins of fundamental noise.
Examples of sensors used in instrumentation systems.
Review of Ohm's Law and Kirchoff's laws in circuit electricity.
Development of equivalent circuits (voltage and current).
Effects of loading.
Review of AC circuits and detailed analysis of simple RC circuit.
Electronic amplifiers and their equivalent circuit.
Input and output resistance, frequency response, noise and cascading of amplifiers.
General characteristics of filters including comparison of passive and active filters.
What is a digital system? How digital systems handle numbers.
Analogue to digital conversion  sampling and quantisation.
Types of converters and the errors associated with them.
Electronic counting devices (systems approach only).
A ten hour practical session will take place throughout the semester to introduce LabView.
