摘要
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.
