In this article, the noise models of recursive digital filters (DF) with lateral feedbacks (LFBs) are presented. The models of four typical schemes DF with LFBs, taking into account the effects of quantization in the individual nodes of the digital filter and rounding errors are considered.

A comparative analysis of noise models for each scheme implementation of DF with LFBs is conducted.
