Description

This unit builds upon fundamentals of electrical engineering and introduces students to advanced topics in electrical networks. Appropriate simulation tools are used extensively both as demonstration and problem solving tools. The concept of the transmission line is introduced, and its applications in real-world engineering systems are discussed. This is followed by investigations of general single- and multi-port electrical networks and electrical filters. Passive and active RC filter implementations are also considered.

Prerequisite Rule

Students must pass 2 units from (ENS1253) AND (MAT1236 OR MAT1250)

Equivalent Rule

Unit was previously coded ENS2455

Learning Outcomes

On completion of this unit students should be able to:

  1. Analyse transmission line circuits and design simple transmission line systems.
  2. Apply appropriate simulation software to the analysis and design of electrical networks.
  3. Derive and make effective use of single- and multi-port network matrix parameters.
  4. Design passive lowpass, highpass, bandpass, and bandstop filters with Butterworth, Chebyshev, Cauer, and Thomson responses.
  5. Design simple active filters using ideal operational amplifiers.

Unit Content

  1. Filter approximations and passive implementations: Butterworth, Chebyshev, Cauer and Thomson approximations, ladder networks, time-domain considerations.
  2. Fundamental concepts of electrical filters: network functions, types of filters, frequency and impedance denormalisation.
  3. Selected advanced filter topics.
  4. Simulation and analysis tools for electrical networks.
  5. Single amplifier active RC filters, second and higher order filters.
  6. Single- and multi-port networks: series and parallel connection of networks, cascading networks, basic matrix parameters, scattering parameters.
  7. The Smith chart: reflection coefficients, impedance and admittance transformations, parallel and series connections, impedance matching.
  8. Transmission line analysis: equivalent circuits, line equations, lossless and lossy lines, termination conditions.

Learning Experience

Students will attend on campus classes as well as engage in learning activities through ECUs LMS

Disability Standards for Education (Commonwealth 2005)

For the purposes of considering a request for Reasonable Adjustments under the Disability Standards for Education (Commonwealth 2005), inherent requirements for this subject are articulated in the Unit Description, Learning Outcomes and Assessment Requirements of this entry. The University is dedicated to provide support to those with special requirements. Further details on the support for students with disabilities or medical conditions can be found at the Access and Inclusion website.

Academic Misconduct

Edith Cowan University has firm rules governing academic misconduct and there are substantial penalties that can be applied to students who are found in breach of these rules. Academic misconduct includes, but is not limited to:

  • plagiarism;
  • unauthorised collaboration;
  • cheating in examinations;
  • theft of other students' work;

Additionally, any material submitted for assessment purposes must be work that has not been submitted previously, by any person, for any other unit at ECU or elsewhere.

The ECU rules and policies governing all academic activities, including misconduct, can be accessed through the ECU website.
