In the paper noise models of nonrecursive digital filters (NDFs) with recursive lateral feedbacks (LFBs) have been presented. Models of four typical schemes of NDF with LFB which take into account quantization effects and rounding errors have been considered. For each scheme of NDF with LFB noise equations for noise dispersion at the output of each channel independent of analog to digital converters (ADC) and multipliers have been deduced. For each scheme of NDF with LFB implementation comparative analysis of noise models have been done.
