The use of redundancy in the structural synthesis of IIR digital filters
Vladislav A. Lesnikov, Tatiana V. Naumovich, Alexander V. Chastikov · 2016
In this paper for implementation of IIR digital filters, it is offered to use structures, which have a number of degrees of freedom significantly more than a number of degrees of freedom of transfer function. Such redundancy allows reducing a length of a fractional part of the filter coefficients without loss of accuracy of transfer function implementation.
