Abstract :
In this paper we present a new digital filter structure which enables a practical realization of finite-wordlength low-sensitivity digital filters. It is a cascade structure consisting of Type I and Type 2 LBR two-pairs interlacing each other, and is called a two-type-interlaced structure. In addition, an LBR test is introduced as a means to determine the LBRness of the quantized two-type-interlaced structure. The proposed structure and the LBR test are applied to the conventional digital filters. The results show that perfect LBRness can always be maintained with the proposed structure
