Aims

This course unit detail provides the framework for delivery in 2020/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

The course unit aims to:

  • Provide a thorough and complete introduction to the subject of modern digital signal processing;
  • Emphasise the links between the theoretical foundations of the subject and the essentially practical nature of its realisation;
  • Encourage and understanding through the use of algorithms and real world examples;
  • Provide useful skills through detailed practical laboratories, which explore both off-line and real-time DSP software and hardware.
