Modular decomposition techniques for stored-logic digital filters

Digital filtering is an important signal processing technique whose theory is now well established. At present, however, there are no well-defined and systematic methods available for realising digital filters in hardware. This project aims to develop such methods which are general and technology independent, and adopts a systems and sub-systems design philosophy. The realisation problem is approached in a new way using concepts from finite-automata theory and implementing complete digital filter sections as stored-logic units. Two methods are introduced and developed. [Continues.]
