Design of Discrete Systems

Module code: EG7016

This module will provide an understanding of the background theory associated with discrete system analysis followed by a review of design methods associated with the main classes of discrete systems. There will be a structured series of lectures and exercise classes. The module will start with a review of the fundamental principles of data conversion and the background theory of discrete signals and systems. Familiarity with continuous linear system theory and complex algebra will be assumed. You will acquire a working knowledge of discrete system analysis and design techniques and will be able to read and understand the extensive literature in this field.
