Cascade realization of linear phase fir filters with low sensitivity

Abstract

The errors due to coefficient quantization in a digital filter are sensitive functions of its pole and zero locations. In this paper, a detailed analysis is made of the sensitivity, with respect to the location of zeros, of elemental fourth-order sections, for cascade realization of linear phase FIR filters. New structures are suggested for the realization of the sections with low sensitivity. Performance analysis of these structures in implementation of a few representative filters indicates their suitability for practical applications. © 1985.
