48530 Circuit Analysis

Requisite(s): 48520 Electronics and Circuits AND 33230 Mathematical Modelling 2
Recommended studies: Students are assumed to have knowledge of basic electrical circuits and devices, e.g. Kirchhoff's Current and Voltage Laws, diodes, energy storage devices and operational amplifiers.
Fields of practice: Electrical Engineering program
Undergraduate
Subject coordinator: Dr Gerard Boardman

Using students' understanding of basic electrical circuits and devices as a starting point, this subject introduces the basic theoretical models that underpin signals and system analysis. Students use analytical modelling to investigate real-world devices. Comparison of experimental results is emphasised in the laboratory sessions; students generally attend three laboratory sessions during the semester.

Topics covered are: ideal and real voltage and current sources and loads; resistors, capacitors, inductors and magnetically coupled coils; mesh and nodal analysis, superposition, circuit transformation; power in AC circuits; Laplace transforms, solution of ODEs using Laplace transforms; one- and two-ports systems; transfer (network) functions; two-port parameters and behaviour; poles and zeros; s-plane analysis; Bode plots; first- and second-order systems – response to periodic and aperiodic inputs; time domain and frequency domain solution; response to an arbitrary input using convolution, resonance; dominant pole approximation and practical system identification techniques.

Assessment: Typically assessment in this subject involves laboratory work, a mid-semester test and a final examination.
