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

Honours students only must pass 1 unit from (MAT1236 OR MAT1250). Additionally, Honours and Master of Technology (T59) students only must also pass 1 unit from (ENS1253 OR ENS6207). There are no pre-requisites required for students enrolled in the Master of Engineering (I59).

Equivalent Rule

Unit was previously coded ENS6165

Learning Outcomes

On completion of this unit students should be able to:

  1. Analyse transmission line systems in order to assess their influence and performance in communication or power systems.
  2. Design transmission lines for use in communication or power systems.
  3. Design passive and active filters for use in analogue communication or power systems.
  4. Apply simulation software to the analysis and design of electrical networks.
  5. Research problems in the field of transmission lines and electrical filters and reflect critically on their significance to electrical engineering.

Unit Content

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

Assessment

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.

Assessment

Students please note: The marks and grades received by students on assessments may be subject to further moderation. Informal vivas may be conducted as part of an assessment task, where staff require further information to confirm the learning outcomes have been met. All marks and grades are to be considered provisional until endorsed by the relevant School Progression Panel.

Academic Integrity

Integrity is a core value at Edith Cowan University, and it is expected that ECU students complete their assessment tasks honestly and with acknowledgement of other people's work as well as any generative artificial intelligence tools that may have been used. This means that assessment tasks must be completed individually (unless it is an authorised group assessment task) and any sources used must be referenced.

Breaches of academic integrity can include:

Plagiarism

Copying the words, ideas or creative works of other people or generative artificial intelligence tools, without referencing in accordance with stated University requirements. Students need to seek approval from the Unit Coordinator within the first week of study if they intend to use some of their previous work in an assessment task (self-plagiarism).

Unauthorised collaboration (collusion)

Working with other students and submitting the same or substantially similar work or portions of work when an individual submission was required. This includes students knowingly providing others with copies of their own work to use in the same or similar assessment task(s).

Contract cheating

Organising a friend, a family member, another student or an external person or organisation (e.g. through an online website) to complete or substantially edit or refine part or all of an assessment task(s) on their behalf.

Cheating in an exam

Using or having access to unauthorised materials in an exam or test.

Serious outcomes may be imposed if a student is found to have committed one of these breaches, up to and including expulsion from the University for repeated or serious acts.

ECU's policies and more information about academic integrity can be found on the student academic integrity website.

All commencing ECU students are required to complete the Academic Integrity Module.

Assessment Extension

In some circumstances, Students may apply to their Unit Coordinator to extend the due date of their Assessment Task(s) in accordance with ECU's Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000001386.

Special Consideration

Students may apply for Special Consideration in respect of a final unit grade, where their achievement was affected by Exceptional Circumstances as set out in the Assessment, Examination and Moderation Procedures - for more information visit https://askus2.ecu.edu.au/s/article/000003318.
