Overview

Signal processing engineers have knowledge of engineering methodologies, and possess problem solving, communication, leadership and project management skills. They design, model, and analyze systems, and use a wide range of technologies and applications, including household appliances, communications systems, modern control, circuit design, biomedical engineering, and speech processing. They help transform society and enhance the quality of life.

This unit will introduce you to the foundations of signal and system analysis in the time and frequency domains. You will learn and work individually and with peers to apply engineering and mathematical concepts and use programming techniques, to solve contextualized practical problems employing Fourier and Laplace analysis, LTI systems, filtering, and System modelling.

This unit will draw on your knowledge and skills from EGB120 and MZB127, and prepare you for units in telecommunications, signal processing and control.

Learning Outcomes

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

  1. Reflect on your experience in developing professional competency, in a signal analysis project, considering relevant risk, sustainability and sociocultural issues, at an introductory level
  2. Compose a technical report of an electrical engineering project including figures, tables, diagrams and code snippets, at a developed level
  3. Perform as a team member to complete a signal analysis engineering study, at an introductory level
  4. Analyse and apply the theory and concepts of time and frequency domain signal analysis, using relevant mathematical and computing techniques and packages such as Matlab, at a developed level

Learning Approaches

Lectures will provide the knowledge base required for this unit including real examples and applications. This will be supported within tutorials, enabling the application of the theory described in lectures. Tutorial sessions will involve problem-solving tasks of increasing complexity to understand, integrate and apply mathematical concepts to signals and systems.

In this unit you can expect to experience the following timetabled activities:

  • Formal lectures from experienced professional engineers to give you insight into professional engineering and mathematical knowledge, skills and attributes,
  • Weekly tutorials, applying the lecture materials of engineering and mathematical concepts to problem solving tasks, and Matlab coding exercises on authentic tasks.

To complement timetabled activities, you will be provided with videos of problem solutions and Matlab exercises.

You are expected to:

  • Weekly problem-solving tasks: you are expected to attempt these on your own, ahead of your tutorials, assisted by the provided video solutions,
  • Weekly Matlab tasks: you are expected to attempt these your own, ahead of your tutorials, assisted by the provided full video solutions,
  • Weekly In-class challenge problem-solving and Matlab tasks: you are expected to attempt these on your own, ahead of your tutorials,
  • In-class quizzes: you are expected to actively participate in attempting the weekly problem-solving and coding tasks, to help you formatively assess your learning, and provide you with feedback on overall-class performance,
  • Matlab Grader exercises: you are expected to attempt these on your own, to formatively assess your own conceptual understanding.

In order to demonstrate individual competency in ULO5, students must achieve 40% in the examination and resubmission is not permitted.

Feedback on Learning and Assessment

You will receive formative oral feedback on your progress in this unit during tutorials and discussions throughout the semester. You will receive written feedback on the unit's problem solving tasks as well as the tutorial and Matlab work. Formative practice and feedback on exam related concepts will also be covered in lectures and tutorials. Additional feedback on a group or individual basis will also be available through appointment with a member of the teaching team.



Assessment

Overview

Assessment in the unit consists of a series of problem-solving tasks throughout the semester of increasing complexity involving signal processing systems and related components. This is reinforced with Matlab exercises to relate theory to practice and a final exam covering all major concepts and learning across the unit.


In order to demonstrate individual competency in ULO5, students must achieve 40% in the examination and resubmission is not permitted.

Assessment Tasks

Assessment: Problem solving assignment

You will design and analyse solutions to problems applying the theoretical concepts and present your results in a report. The assignment can include hand-written solutions. The design and analysis will rely on the use of Matlab.

Weight: 25
Individual/Group: Individual
Due (indicative): Week 7
Related Unit learning outcomes: 1, 2, 4

Assessment: Group assignment

You will design and analyse solutions to a significant problem and present your results in a report. The design and analysis will rely on the use of Matlab.

Weight: 35
Individual/Group: Group
Due (indicative): Week 12
Related Unit learning outcomes: 1, 2, 3, 5

Assessment: Examination (written)

This tests all of the major concepts covered in the unit including principles, problem-solving, and analysis of signals, systems, and transforms.

On-Campus invigilated Exam. If campus access is restricted at the time of the central examination period/due date, an alternative, which may be a timed online assessment, will be offered. Individual students whose circumstances prevent their attendance on campus will be provided with an alternative assessment approach.

Threshold Assessment:

To pass EGB242 you are required to achieve at least 40% of the available marks in the final exam. This is to ensure you have a demonstrated understanding of the key concepts of the learning outcomes. This understanding is essential for future units in signal processing, telecommunications and control. 

Weight: 40
Length: Exam type will be set to Theory 1.
Individual/Group: Individual
Due (indicative): End of semester
Related Unit learning outcomes: 4, 5

Academic Integrity

Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.

Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.

You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.

Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.

Resources

You will be assisted with lecture notes, and other written and or video recorded resource materials. You will also be referred to a number of reference books in signals, systems and control. The unit's Canvas site will provide access to various resource materials.
