This unit provides foundation knowledge for analogue circuit analysis and design. Students will be introduced to the fundamentals of linear electronic circuit analysis and design. At the completion of the unit students will develop skills in using state of the art prototyping and measurement tools for linear electronic circuit analysis and design. The topics covered in this course include, sinusoidal steady-state analysis using phasors and complex impedances, feedback concepts, solid-state electronics, solid-state diodes and diode circuits, field-effect transistors, bipolar junction transistors and operational amplifiers.

The unit will provide a grounding in circuit theory leading to solution of electrical networks with node and mesh analysis, equivalent sources, two port representations and simulation. AC analysis with phasors, first and second order transient responses will be included. Frequency and time response will be developed with Laplace transform techniques.


On successful completion of this unit, students will be able to:

  1. Separate and classify DC and AC electrical circuits, to generalise and solve problems in design by applying circuit analysis techniques and create appropriate circuit layouts.
  2. Write and compute circuit simulations, reflecting upon simulation outputs to conclude upon appropriate designs.
  3. Identify appropriate techniques to provide solutions for the transient response of first and second order electrical circuits, and make conclusions on circuit design based upon these results.
  4. Generalise the behaviour of key semiconductor electronic components (diodes, transistors, operational amplifiers) in circuits and to summarise their uses.
  5. Compute and generalise the behaviour of RLC circuits.


Continuous assessment: 40%

Examination (2 hours): 60%

Students are required to achieve at least 45% in the total continuous assessment component (assignments, tests, mid-semester exams, laboratory reports) and at least 45% in the final examination component and an overall mark of 50% to achieve a pass grade in the unit. Students failing to achieve this requirement will be given a maximum of 45% in the unit.

Workload requirements

3 hours lectures, 3 hours laboratories/tutorials and 6 hours of private study per week.
