Central to the profession of all electrical engineering professionals is the measurement of electrical quantities. More generally this relates to physical quantities whose values have been rendered electrical by a transducer. Such measurements are almost invariably made with the aid of electronics, and increasingly by sophisticated instrumentation which provides multidimensional displays and analytical capabilities.
Through a clear understanding of the physical principles of electrical measurement, students will design effective measurement systems, benefiting the quality of the measurement, as well as industrial systems. This course follows on from ELE2501, ELE2503, and ELE2504, advancing these techniques.

Students will comprehend the physical principles of making accurate, precise and trustworthy measurements, particularly of small quantities (microvolts, microamperes). They will be able to specify and evaluate equipment for a given measurements task, requiring an appreciation of electronic measurement systems. At the system level students will have an awareness of the range, operating principles and limitations of commercial test equipment. At the circuit level students will understand the effects and minimisation of interference, configurations of certain commonly employed circuits such as the Phase Lock Loop and frequency synthesis, and the choice of components and construction details. Students will also study elements of electromagnetic compatibility, as well as implementation of measurement systems regarding human and environmental impacts.

The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:

1. discuss the operating principles of common electronic laboratory test equipment;
2. apply the principles of operation of common electronic measuring equipment, and to assess the limitations of that equipment;
3. measure the performance of electronic test equipment and electronic circuits;
4. design appropriate techniques for minimising signal interference;
5. select and justify amplifiers appropriate to an application;
6. design, construct and evaluate electronic circuits for low-signal, high-interference environments;
7. analyse the performance of Phase Lock Loops and calculate their parameters;
8. discuss the principles of reliability theory as applied to electronic systems, and calculate composite reliability and subsystem redundancy;
9. discuss human and environmental implications of measurement systems.
