Summary:
This paper discusses the effects of finite wordlength realization on frequency responses of all-pass fractional delay digital filters. To this end, this paper focuses on analysis of coefficient sensitivity of all-pass fractional delay digital filters over several specific filter structures. In addition, it is shown that the normalized lattice structure gives the optimal solution to the sensitivity minimization for all-pass fractional delay digital filters.
