Abstract
Abstract A circuit for ergodic processing periodic and aperiodic signals with an ergodic converter comprised of a threshold value controlled decision unit and a periodic threshold signal generator, a filter connected to the converter output and a regulation signal generator connected to the filter for receiving the filtered signal and to the threshold generator for causing the threshold generator to generate periodic threshold values of different frequencies to ensure statistical independence of the threshold value signal and any periodic input signal.
