Module Study Targets

This course will develop digital signal processing (DSP) theory and methods with the following objectives:

  • Understand the significance of digital signal processing in multi-media technology, storage and communications
  • Familiarity with fundamental concepts such as ‘linearity’, ‘time-invariance’, ‘impulse response’, ‘convolution’, ‘frequency response’, ‘z-transforms’ and the ‘discrete time Fourier transform’ as applied to signal processing systems
  • Knowledge of digital filters and their application to digitised sound and images
  • Understand how FIR and IIR type digital filters: may be designed and implanted in software
  • Use the “MATLAB” language and “signal processing toolboxes” for designing, implementing and simulating digital signal processing (DSP) operations as applied to speech, music and images
  • Understand analogue/digital conversion as required for the digital processing of analogue signals
  • Understand the discrete Fourier transform (DFT), its applications and its implementation by FFT techniques. Gain some knowledge of the 2-D FFT and its application to image processing and compression
