##### Course Learning Outcomes
At the end of this course, the student would be able to
1. Describe and explain the basic models that underpin digital signal processing methods including discrete time linear systems and signals, digital filters and random processes.
2. Choose and apply suitlable technique(s) to estimate the spectrum from a signal's time series.

##### Online Learning
This course uses a variety of online resources to support learning, including:
• slides, demo documents, example code and tutorial questions
• assessment tasks, including past material and/or exemplars
All course communications will be made via the MyUni site.

The use of the online discussion boards is strongly encouraged for questions related to course content.

The course gradebook will be used to return continuous assessment marks. Students should check the gradebook regularly and confirm their marks have been correctly entered.
• Learning & Teaching Activities
##### Learning & Teaching Modes
This course uses face-to-face workshops and tutorials, supplemented by online materials, to achieve its learning objectives.

There are pre-assigned readings each week, which students are expected to complete; key concepts and techniques are emphasised with written notes. Workshops involve short, class-wide discussions on the assigned reading, followed by small-group work on a variety of problems. These are typically completed in Matlab. There is a small assessment component for active participation in tutorials.

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

There will be up to 30 contact hours throughout the course. Students are expected to spend approximately 120 hours of private study, preparing for tutorials, completing assignments and revising for tests.

• 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.

• 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.

This course is offered for the first time in 2022.
• 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 studentâ€™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.
