Signal distortions in comparator pulse gate transformation using the statistical method for a low number of samples

Distortions during comparator pulse gate transformation of noisy signals are analyzed using the statistical method and its variants. The distortions are characterized with a systemic error in measuring the input signal??s amplitude. The studies are carried out for a low number of operations of comparing a signal with a constant threshold. Systemic errors of the main statistical method and error correction methods are compared. It is shown that the correction ensured using the combined approach is almost ideal. The results of the studies can be used in ultrawideband radio detection (UWB).
