Requisites
Pre-requisite: (ELE1502 and (ELE2101 or ELE2103) and (ELE2503 or ELE2504)) or Students must be enrolled in one of the following Programs: GCEN or METC or MEPR or MENS
Rationale
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.
Synopsis
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 with regard to human and environmental impacts.
Objectives
The course objectives define the student learning outcomes for a course. On completion of this course, students should be able to:
- discuss the operating principles of common electronic laboratory test equipment;
- apply the principles of operation of common electronic measuring equipment, and to assess the limitations of that equipment;
- measure the performance of electronic test equipment and electronic circuits;
- design appropriate techniques for minimising signal interference;
- select and justify amplifiers appropriate to an application;
- design, construct and evaluate electronic circuits for low-signal, high-interference environments;
- analyse the performance of Phase Lock Loops and calculate their parameters;
- discuss the principles of reliability theory as applied to electronic systems, and calculate composite reliability and subsystem redundancy;
- discuss human and environmental implications of measurement systems.

Important assessment information
-
Attendance requirements:
It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administrations. This course contains a discussion forum where students' participation is formally assessed and successful participation in that discussion group is required to complete the requirements to be awarded a passing grade in the course. -
Requirements for students to complete each assessment item satisfactorily:
To satisfactorily complete an individual assessment item, a student must achieve at least 50% of the marks or a grade of at least C-. -
Penalties for late submission of required work:
Students should refer to the Assessment Procedure (point 4.2.4) -
Requirements for student to be awarded a passing grade in the course:
To be assured of receiving a passing grade in a course a student must obtain at least 50% of the total weighted marks for the course. -
Method used to combine assessment results to attain final grade:
The final grades for students will be assigned on the basis of the weighted aggregate of the marks (or grades) obtained for each of the summative assessment items in the course. -
Examination information:
There is no examination in this course. -
Examination period when Deferred/Supplementary examinations will be held:
There will be no Deferred or Supplementary examinations in this course. -
精东传媒app Student Policies:
Students should read the USQ policies: Definitions, Assessment and Student Academic Misconduct to avoid actions which might contravene 精东传媒app policies and practices. These policies can be found at .
