  • Learning & Teaching Activities
    Learning & Teaching Modes
    This course relies on lectures as the primary delivery mechanism for the material. Tutorials supplement the lectures by providing exercises and example problems to enhance the understanding obtained through

    lectures. Computer exercises are used to provide hands-on experience for students to reinforce the theoretical concepts encountered in lectures. Continuous assessment activities provide the formative assessment opportunities for students to gauge their progress and understanding. The subject material falls into 6 major topics. The final topic is presented as an extended computer-laboratory exercise. Lectures: lecture slides will be available prior to lectures and, where material outside of the scope of the textbook is presented, detailed notes will be provided. Students will be encouraged to read sections of the course textbooks in preparation for lectures.

    Tutorials: these will give students an opportunity to practice through the solution of a set of problems. The problems will be available prior to the tutorial and students will be expected to prepare by answering whatever problems they can, and by framing questions to assist them solve the remaining problems. During the tutorial students will work together and with the assistance of tutors to solve remaining problems.

    Computer Exercises: these will be undertaken as individuals in a computer suite. A worksheet of exercises will introduce students to the C programming language, use of the Wind River Workbench and VxWorks real time operating system. These will be strongly structured. Extended Computer Exercise: the final topic, Real Time Adaptive Filters, is presented as a project based exercise in which students develop software to solve a real-time problem using the C programming language in the VX-Works environment. The problem will be specified in terms of a required function. Some lecture time-slots serve for this topic will serve as discussion forums in which students can raise questions and seek guidance from the lecturer. This exercise will be less strongly guided than the other exercises. The aim is to stimulate different possible solutions to a well-defined problem.

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Assessment Related Requirements
    There are no special requirements.
    Assessment Detail
    Details of individual assessment tasks will be provided during the semester.
    Computer exercises will be assessed during the computer session. The final computer-based exercise will be assessed by demonstration during a marking held in one of the computer-laboratory time-slots. Students can expect the grades from continuous assessment components to be available on MyUni within two weeks from the submission deadline.

    According to the School of Electrical and Electronic Engineering’s policy on Homework and Assignment Submissions (https://www.eleceng.adelaide.edu.au/policies/homework-assignment-policy.pdf), submission of the computer exercises or PBL exercise will not be accepted after their deadlines unless accompanied by documentary evidence of an unavoidable reason for the delay. The

    School’s policy on Supplementary Exercises for Continuous Assessment Components (https://www.eleceng.adelaide.edu.au/policies/continuous-assessment-exercises.pdf) applies to the quiz, computer exercises and PBL exercise.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
