Learning & Teaching Activities
Learning & Teaching ModesThis course relies on face to face sessions as the primary delivery mechanism for the material with video lectures and quizzes being used to supplement the face to face lectures. Exercises provide practice in problem solving and enhance the understanding of the course topics. The 4-week practical is used to provide hands-on experience for students to reinforce the theoretical concepts encountered in this course. Marked homeworks and tests provide formative and summative assessment opportunities, respectively, for students to measure their progress throughout the semester.
The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

Specific Course RequirementsStudents are required to have access to Matlab software. This is available at various facilities such as the CATS suite or the undergraduate computer labs of the School of Electrical & Electronic Engineering. It is the individual student’s responsibility to ensure his or her access to these facilities at appropriate times is available.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment activity Type Weighting Due date Learning objective addressed Homeworks Formative 16% Weeks 4, 6, 8, 11 1-6 Tests Summative 14% Weeks 5, 10 1-6 Practical Formative 10% Weeks 5-8 3 Exam Summative 60% End of semester 1-6
Assessment Related RequirementsThe examination is a hurdle requirement. It is necessary to achieve at least 40% in the exam. If this is not achieved, the total course mark will be limited to a maximum of 49.
A hurdle requirement is defined by the University's Assessment for Coursework Programs policy as "...an assessment task mandating a minimum level of performance as a condition of passing the course.
If a student fails to meet a hurdle requirement (normally no less than 40%),and is assigned a total mark for the course in the range of 45-49, then the student is entitled to an offer of additional assessment of some type. The type of assessment is to be decided by the School Assessment Review Committee when determining final results. The student’s final total mark will be entered at no more than 49% and the offer of an additional assessment will be specified eg. US01. Once the additional assessment has been completed, this mark will be included in the calculation of the total mark for the course and the better of the two results will apply. Note however that the maximum final result for a course in which a student has sat an additional assessment will be a “50 Pass”.
If a student is unable to meet a hurdle requirement related to an assessment piece (may be throughout semester or at semester’s end) due to medical or compassionate circumstances beyond their control, then the student is entitled to an offer of replacement assessment of some type. An interim result of RP will be entered for the student, and the student will be notified of the offer of a replacement assessment. Once the replacement assessment has been completed, the result of that assessment will be included in the calculation of the total mark for the course.
Assessment DetailThe homeworks require students to submit written responses to selected sets of problems. The submissions may contain any of the following: written answers, mathematical derivations, sketches, graphs and print-outs from appropriate software packages. There will be four separate problem sets, each worth 4% to the overall assessment.
There are two 45-minute closed book quizzes in the course. The quizzes will require students to submit short written responses to a set of questions under examination conditions. Each quiz will be worth 7% to the overall assessment.
The practical needs to be conducted during the designated laboratory sessions as listed in Section 1.3 Course Timetable. Students will be required to show regular progress in the laboratory sessions, and to submit a practical report describing the practical work for assessment. The combined total of in-lab progress marks and the practical report are worth 10% of the final assessment.
The exam will be a closed book examination. It will be worth 60% of the overall assessment.
SubmissionAll written submissions to formative assessment activities are to be submitted electronically, or to designated boxes within the School of Electrical & Electronic Engineering, by 3.00pm on the due date and must be accompanied by a signed cover sheet. Copies of blank cover sheets are available from the School office in Ingkarni Wardli 3.26, or online in electronic form. Late submissions are not accepted unless explicit prior approval is granted by the course coordinator or Head of School. All in-term assessments will have a two week turn-around time for provision of feedback to students.

Final results for this course will be made available through Access Adelaide.
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.

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.
