Full Title:DSP Implementation
Language of Instruction:English
Module Code:ENGR E7005
 
Credits: 5
Valid From:Semester 1 - 2009/10 ( September 2009 )
Module Delivered in 1 programme(s)
Module Description:This module follows on from DSP Design. Whereas DSP Design uses Matlab running on a PC to model algorithms, this module considers the issues involved in implementing DSP algorithms using a single chip solution. The chip or IC might be a FPGA a microcontroller or a DSP processor.
Learning Outcomes:
On successful completion of this module the learner should be able to
  1. Compare different chip architectures from the point of view of implementing selected DSP algorithms.
  2. Assess how the parameters of the 'Front End' of a DSP system can impact on the overall quality,in terms of the SNR of the resultant outputs.
  3. Calculate the values of numbers represented in different binary formats, such as unsigned,signed,fixed and floating.
  4. Design a digital filter from a given specification.
  5. Implement a DSP algorithm or digital control algorithm on suitable digital platform such as a microcontroller.
  6. Apply the DFT algorithm using suitable PC based software such as Matlab.
