If the day/time is changed, the students will be informed in the class and the new arrangement will be posted on MyUni.

To provide student with a good understanding of some important electronic components, their circuit behaviours, and applications in the analogue processing of electronic signals and to show how these circuits have been used in various real-life applications. On completion of the course, students should:

Text book:

• Hambley, A.R., Electrical Engineering – principle and applications, 4th edition (International edition), Prentice Hall, 2007 or later edition (available from Unibooks);
• Lecture notes available as printed copy from the Image & Copy Centre at the beginning of the semester and electronic copy available via MyUni.

Wesley, A., Electronics – A System Approach, 2nd edition, 1998.

Course related materials including announcements, lecture notes, tutorial materials, practical information and so on will be made available in . Students are asked to access regularly (preferred at least once a week) for the course related information and materials throught out the semester.

• Lectures to cover the contents described in Section 1.1 course description and enhanced by tutorial questions, circuit simulations and practicals.
• Tutorials to support the covered contents adopting problem-solving principles.
• Assignments for students to exercise the knowledge learned.
• Simulations and practicals to integrate and apply the contents covered in the lectures to realise functional circuits.

In addition to averaged about five hours a week for lectures, tutorial and practical activities, averaged three hours per week are estimated to be necessary to review the contents learned and work on assignments, tutorial questions and practical reports to achieve good learning results.

Not applicable.

• Assignments 20%: to exercise and apply the individual topic knowledge learned; learning outcomes addressed 1, 2, 3, 4, 5, 6 and 7;
• Practicals 10%: to integrate, exercise and apply the learned knowledge to simulate and realise various circuits as well as to learn the use of electronic instruments; learning outcomes addressed 1,3 4, 5, 6 and 8;

Continuous assessment is required which needs the students to pass the assignments (averaged) and practicals (averaged) to sit for the final examination.

• Assignments: Assignments will be set and related to the topics described in Section 4.3 learning activity summary.
• Practicals/Simulations: The use of electronic instruments, RC circuits, operational amplifiers, diode circuits, BJT circuits, FET circuits, and PSPICE simulations will be carried out.
• Final exam: The final exam will be set to test the electronic knowledge learned.

Assignments and project report (hardcopy) need to be submitted with cover sheet to the submission box, which has the correct course label, located on level 2 of Engineering South Building before the deadline. Electronic copies of practical reports as well as simulation files (PSPICE .sch files) need to be submitted to the email address that will be specified at the beginning of the semester. Every one day late submission (both assignments and practical reports) will incur 10% mark deduction. Due dates may be extended with genuine reasons which needs to communicate with the lecturer face-to-face or by emails. The turn-around timeline on assessments and the provision of feedback is two weeks after the submission deadline.
