Sample subject outline - Semester 2 2013
Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Many physical systems can be analysed and designed using linear analysis techniques. This assists in the understanding of the behaviour of many systems and interactions with them. The linear systems analysis techniques studied in this unit will be applied to physical systems in general with a greater emphasis on electrical circuits and systems. The skills gained in this second year unit build upon your first year studies in mathematics and introductory electronics to form the platform for further studies and career development in analogue circuit design, signal processing and control systems.
Aims
An aim of this unit is to develop skills to analyse physical systems using linear analysis techniques, to characterise these systems and to apply these techniques in particular to electrical circuits for filtering and signal conditioning applications. You will also develop skills in team work, communication with peers at a technical level and to interpret technical data.
Objectives
On completion of this unit, you should be able to:
1. Demonstrate how to model linear systems and networks
2. Determine and communicate linear systems characteristics in the time and frequency domains
3. Analyse and design linear filters using operational amplifiers
Content
1. Complex frequency domain (Laplace) analysis techniques and characteristics
2. Linear systems analysis and characteristics
3. Operational amplifiers and active filters
4. Circuits and applications
Approaches to Teaching and Learning
Teaching Mode: Hours per week: 4
Lecture: 2
Computer lab and laboratory: 2
Both technical and generic capabilities will be developed through interactive lectures, laboratories and tutorial sessions. Laboratory sessions and tutorials will have prescribed problems which will be supported through peer tutors and laboratory demonstrators. Self-learning exercises will be prescribed based on computer-based tools to enhance circuit analysis and simulation skills. A rich learning environment will be provided on-line using Blackboard.
Assessment
Assessment includes quizzes, assignment work, laboratory work and a final examination will promote required knowledge and skills.Formative oral and written feedback will be offered by the lecturer, tutors and laboratory demonstrators during the semester at key times to assist you in the development of your skills. You will also receive written feedback on problem solving tasks.

Risk assessment statement
You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.
You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the Faculty. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).
You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card, you will be denied access to laboratories.
Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
