Speed of operation of equivalent time methods for conversion of noisy signals: A review

Based on the example of the conversion of noisy UWB radar signals, the speed of operation of comparator-type methods for equivalent time conversion of signals is compared. As a signal model, a sine monocycle is used. The obtained results are also compared with the efficiency of noise suppression in gated equivalent time converters. As a measure of the speed of operation of comparator-type converters, the minimal number of comparison operations of the signal and the threshold required for reaching the specified sensitivity and dynamic range is used. As a measure of the speed of operation, the number of averagings required for reaching the specified sensitivity is used for gated converters.
