Sensitivity of hybrid filter banks A/D converters to analog realization errors and finite word length

Abstract

This paper studies the sensitivity of hybrid filter banks (HFB) to analog inaccuracies and finite word implementation. It is shown that very small errors affecting very simple analog structures have a dramatic influence on the performances of the HFB. The influence of the quantization of digital filter coefficients is also studied. A theoretical limit for the error introduced by the quantization of digital filter coefficients is derived.
