Abstract

The authors present a new digital filter structure which shows a low-sensitivity property. It is a cascade structure consisting of Type 1 and Type 2 LBR two-pairs interlacing each other, and is called a two-type-interlaced (TTI) structure. In addition, a test procedure called an LBR test is introduced as a means to determine the LBR-ness of the quantized TTI structure by checking the LBR-ness of the residual Type 1 two-pair in the associated Type 3 re-assembled structure. Computer simulation confirms that this new structure exhibits a much improved sensitivity characteristic over the other existing structures
