ENEE12016 - Signals and Systems

General Information

Unit Synopsis

Electrical systems are fundamental to our way of life, including electrical power, telecommunications and automatic control systems. In this unit, you will learn mathematical techniques to analyse and design a wide range of these electrical systems, such as electrical power distribution and transmission networks and control systems. You will be introduced to the concept of linear time invariant systems and a range of mathematical tools used in electrical circuit analysis such as forward and inverse Laplace transforms, s-domain circuit analysis and transfer functions. You will be also introduced to the frequency response of a system and you will identify different types of filters and design analogue filters for given specifications. Through this unit, you will gain hands-on experience in circuit construction and performance analysis in laboratory sessions and through the use of circuit simulation software. This unit will also provide you with opportunities to further develop communication skills through preparation of professional documentation and team communications. All students are required to have access to a computer and to make frequent use of the Internet. Students enrolled in distance mode are required to attend a compulsory Residential School.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 15%
2. Written Assessment 15%
3. Practical and Written Assessment 20%
4. Examination 40%
5. Online Quiz(zes) 10%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Unit survey
Feedback
The lectures and tutorials are very long, making them hard to learn in one go.
Recommendation
Break the lectures and tutorials into sizable chunks based on logical concepts and topics to allow easier digestion of materials.
Action Taken
Nil.
Source: Unit survey
Feedback
A computational modelling maths unit perhaps should be a prerequisite and provided to better prepare students for using Matlab in this unit.
Recommendation
Discuss with the School management to make MATH12225 - Applied Computational Modelling a prerequisite for the unit.
Action Taken
Nil.
Source: Unit survey
Feedback
The textbook while very thorough is very cumbersome to get through.
Recommendation
Consider replacing the current textbook with a new one that focuses more on practical guidance rather than theoretical rigorousness and abstraction.
Action Taken
Nil.
Source: Unit survey
Feedback
Although very comprehensive, the assessment workload was very high. Especially since the labs were too long, they took significant time to do, affecting the available valuable learning time for the lectures and tutorials.
Recommendation
Revise assessments and labs to streamline and reduce the length and the number of pieces without compromising on their thoroughness.
Action Taken
Nil.
Source: SUTE
Feedback
Student queries through emails and forum posts were promptly addressed.
Recommendation
This good practice should be continued.
Action Taken
Student questions and queries in Q&A forum and emails were promptly answered.
Source: SUTE
Feedback
Lectures were interactive and detailed explanations on contents were provided during lectures.
Recommendation
This good practice should be continued.
Action Taken
This practice was adopted for this term.
Source: SUTE
Feedback
Time taken for lecturing was too long, which drastically reduced the time spent on tutorials.
Recommendation
Better time management should be maintained.
Action Taken
The lectures were revised and sectioned into several key concepts to reduce length and more elaborative questions were given in the tutorials to help students apply the theories.
Source: SUTE
Feedback
The labs were extraordinarily fast-paced and constantly interrupted by code just not working. The reason being students did not know what add-ons were to be utilised.
Recommendation
Better initial preparations should be made with MATLAB programming exercises.
Action Taken
Codes were checked before the residential school to ensure they worked well. Step-by-step instructions were given to students during the lab session to ensure everyone could follow.
Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Explain the concepts of a linear time invariant system, unit impulse and step functions, convolution integral and convolution sum
  2. Apply forward and inverse Laplace transforms and analyse electrical circuits in the s-domain
  3. Identify and design different analogue filters
  4. Perform Fourier transforms to find frequency domain representations of time domain functions
  5. Use laboratory procedures and appropriate simulation tools to validate the analysis techniques
  6. Create professional documentation of the solutions, designs and analysis process using electrical terminology, diagrams and symbols that conform to Australian Standards
  7. Work individually and collaboratively in a team to produce high quality outputs

Learning outcomes are linked to Engineers Australia Stage 1 Competencies and also discipline capabilities. You can find the mapping for this on the Engineering Undergraduate Course website.
