EFFECT OF CASCADE DIGITAL FILTER HIGH ORDER FEATURES ON ITS ROUNDOFF NOISE
Abstract:

Considered the influence of features of a high order cascade filter to the output quantization noise, obtained the formula of output roundoff noise dispersion, which takes into account the averaged values of the gain of the  cascade and quantization noise. Proposed order of the filter section taking into account values averaged coefficients filter section based on the control output of the quantization noise, which reduces the output quantization noise.
