EE3-07 Digital Signal ProcessingLecturer(s): Dr Patrick Naylor
To present the fundamental principles and applications of Digital Signal Processing
To enable students to gain an appreciation of sampling theory, z-transforms and system functions; to analyse and design digital filters using signal flow graphs, elementary FIR/IIR filter design techniques, windows and bilinear and band transformations; to gain an appreciation of discrete Fourier transforms; to perform and interpret correctly the results of simple and short-time spectral estimation; to see fast computation of the DFT as decimation -in-time; to gain an appreciation of linear, cyclic and sectioned convolution in the context of digitial filtering and to implement (fast) filtering algorithms; to develop basic multirate signal processing elements and identities and to see them applied in typical applications; to analyse and design sample rate changing systems; to implement multirate signal processing systems using polyphase representation of filters; to gain an appreciation of maximally decimated filter banks, their limitations and the sources of errors therein; to see, in overview, microprocessor architectures for DSP; to consider the implementation aspects of simple DSP algorithms.
