8 credits, NQF Level 7


The principal aim of this module is to provide students with the basic tools required for understanding linear systems, and the effect that such systems have on deterministic signals.


On completion of the module, students will be expected to be able to:

1Find the Laplace equations in s for simple RLC circuits, and solve them to find a transfer function.
2Calculate the inverse Laplace transform by making use of partial fractions.
3Find the frequency transfer function by letting s = j?.
4Sketch Bode plots: for a given transfer function, the magnitude and phase responses as functions of frequency
5Determine the Fourier series of a periodic signal, and sketch its magnitude and phase spectra.
6Calculate the Fourier transform of an aperiodic signal, and sketch its magnitude and phase spectra.
7Establish how a simple RLC circuit affects an input signal’s magnitude and phase.
8Interpret and use two-port representations of a network, and convert between representations
9Implement of techniques by means of computer software

Workload requirements

This module concentrates on a very important tool for the electronic engineer, namely the Fourier transform, and considers both its theoretical properties and practical applications. The module uses the Fourier transform primarily to study basic communication systems in the time and frequency domains. There will be a combination of lectures that include interactive elements, practical assignments to include application aspects of signals and systems, tutorials in which students will do individual work (self-assessments; reflecting on learning aspects), group work (PowerPoint presentations on aspects of the module, role-play and group discussions), Moodle, for sharing learning aids, to help students test their own knowledge through informal quizzes, and to administer short formal tests; and the Flipped Classroom approach for certain aspects of the course. All outcomes will be assessed by means of tutorial work, quizzes, laboratory work, class tests and a final examination.
