Abstract

An analysis of the delay requirements for rational sampling rate conversion systems is presented. Two transformation rules are derived to minimize the total number of delay units in the system. Using the two rules, a parameter formalized three-dimensional structure with minimum delay requirements can be achieved. This structure is particularly suited to a time multiplexed implementation which allows fewer arithmetic operators and data stores to be built in hardware as compared with a direct implementation of the polyphase structure
