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 electrical systems, such as communication, electrical power distribution, and transmission and control systems. You will be introduced to the concept of linear time-invariant systems and several mathematical tools used for system analysis, especially electrical system analysis, such as forward and inverse Laplace transforms, s-domain circuit analysis, and transfer function. You will also be introduced to the frequency response of a system, identify filter types, and design filters for given specifications. Through this unit, you will gain programming experience in using simulation software to analyse signals and linear systems. This unit will provide you with the opportunities to further develop communication skills through developing technical documentation and reports. All students must have access to a computer, frequently use the Internet, and complete the compulsory practical activities. Furthermore, the unit also aims to promote the UN sustainable development Goal 9 - Build resilient infrastructure, promote inclusive and sustainable industrialisation, and foster innovation by developing an understanding of how to build resilient and sustainable automation and intelligence systems to support industrial innovation.

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. Online Quiz(zes) 30%
2. Practical and Written Assessment 30%
3. Written Assessment 40%

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
Class breaks were introduced to separate distinct concepts and give students short rest periods.
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
MATH12225 - Applied Computational Modelling was a prerequisite for the unit, and the ALC provided math support for students.
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
A new textbook, Electric Circuits, Global Edition (11th edition) by James W. Nilsson and Susan Riedel, was adopted.
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
The number of assessments was reduced to three, with the content realigned to align with learning outcomes and streamlined.
Source: SUTE
Feedback
The use of a document camera for solving tutorial questions was highly appreciated.
Recommendation
This practice should be continued in future offerings.
Action Taken
In Progress

Feedback
The difficulty level of the final assessment should be adjusted to align with the expected unit learning outcomes.
Recommendation
The final assessment should be reviewed and adjusted to match the expected level of learning outcomes.
Action Taken

Feedback
Materials should be better aligned with assessment to promote effective learning.
Recommendation
A more direct alignment between learning content and assessment should be established.
Action Taken

Feedback
The unit content was extensive, causing class sessions to run over time.
Recommendation
The unit content should be streamlined to ensure class sessions stay within the allocated duration.

The relevance of the unit content to the degree should be communicated to students.
Recommendation
The relevance of the unit content to the degree and future career should be explained to students during class.
Action Taken

Feedback
The unit requirements could be clearer.
Recommendation
More detailed instructions about the unit requirements and assessments should be provided to students in class, as well as the assessment materials.
Action Taken
In Progress
Source: SUTE
Feedback
Assessment feedback for online quizzes should be more detailed to enhance understanding.
Recommendation
Online quiz assessments should provide more descriptive feedback with clear connections to the learning materials.
