Noise suppression for recursive RNS filters

摘要

The output of recursive filters using residue number system should be scaled. It can be carried out by conversion to mixed radix system proposed by F. J. Taylor. He also showed that such conversion is easy and practical when the residues are of 2{sup}n - 1, 2{sup}n and 2{sup}n + 1. This paper describes a method to suppress scaling noise of such filters.
