Abstract

Circuitry having at least two stores for the periodical storage of instantaneous values of at least two similar stochastic signals, at least two comparison circuits for comparing during a comparison time interval the stored values with subsequently occurring values of the other signal and for the formation of two positive functions depending on the comparison results, a device for the temporal integration of the differences of the two functions, and a device for indicating the sign of the result of the integration thus providing a determination of the direction of the mutual temporal shift T of the two stochastic signals.
