This module covers circuit theory and analysis of transient and steady-state AC responses of RC, RL, and RLC circuits using complex analysis and phasors. Students will learn to explain the concept of phasors, apply complex analysis to circuit design, and design passive and active filters. Assessment includes problem sheets, lab reports, and a 2-hour closed-book exam.

Learning outcomes
On completion of this module, students should be able to ...
- explain the concept of a phasor and the use of phasors to describe phase differerences between voltages and currents in an
electronic circuit;
- apply complex analysis to the description and design of circuits with resistors, capacitors and inductors;
- design low-pass, high-pass, band-pass and band-stop filters.
