Objectives The general aim of this subject is to introduce students to the concepts that underpin instrumentation and measurement. Experimental skills associated with analog and discrete signals and systems are also emphasised in the practical sessions. At the successful conclusion of this subject students will be able to build on their knowledge of analog and discrete signals and systems and associated types of instrumentation; obtain a grounding in various types of signals, their processing, coding and transmission; understand how signals are transmitted and the manner in which noise may be reduced; understand some of the relevant electrical and magnetic properties of modern materials; enhance their capability to use computers as a form of physical instrumentation; achieve competency in the application of these techniques in the laboratory.
Synopsis The four theory units are (1) Signal processing: Fourier concepts, convolution, analog and pulse modulation, sampled signals, signals and noise. (2) Electromagnetism: Properties of electromagnetic waves, transmission lines, guided waves. (3) Computer interfacing: Logic, handshaking, serial and parallel systems, synchronous and asynchronous systems, common busses used in instrumentation. (4) Materials properties: Periodicity and reciprocal space, structures and symmetry, x-ray diffraction, electronic and magnetic properties of solids.
