Summary module description:

This module aims to show how information theory concepts can be applied to noisy channels, continuous sources and communications systems, and to introduce how Fourier and Laplace transform techniques can be used to describe and analyse signals. This module also introduces the topic of Digital Signal Processing (DSP).

Assessable learning outcomes:
An ability to quantify information transfer in noisy channels, continuous sources and communications systems. An ability to explain, apply and design coding techniques to minimise errors. An ability to apply fundamental concepts to describe and analyse signals.
An understanding of the key advantages and disadvantages of processing in the digital domain as compared to the continuous analogue domain. To be able to describe the structure of a classical DSP system and the application of DSP. To be able manipulate difference equations and Z-transforms of systems in order to find the impulse and frequency response of systems. To be able to use design tools to design filters and similar systems.

Additional outcomes:
Design and analysis of information coding systems; signal analysis.

Penalties for late submission:
The Module Convenor will apply the following penalties for work submitted late, in accordance with the University policy.

  • where the piece of work is submitted up to one calendar week after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for the piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of five working days;
  • where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

  • The University policy statement on penalties for late submission can be found at:
    You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
