Error spectrum shaping structures for digital filters
Abstract
This paper presents roundoff noise expressions for fixed-point digital filters realized in the error spectrum shaping structure which is a generalization of the error feedback structure. A comparison of this structure with other low roundoff noise digital filter structures in terms of output roundoff noise variance will also be presented
