Abstract

PURPOSE:To prevent pulse trains of two systems from being eliminated erroneously simultaneously, by causing a unit to output a signal reporting that existence of the system of a certain pulse train has been confirmed. CONSTITUTION:The pulse train cycle discrimination operation of the succeeding- stage circuit which has received a signal from the input circuit is performed by measuring the time interval between two adjacent pulses and by detecting whether the third pulse having an interval equal to measured time interval gamma exists in the mixture signal or not. When a pulse which is time gamma away from the latter pulse out of pulses, which have the time interval measured, is found, a confirmation signal is output, and a pulse train of a single period and a gate signal selecting only the system which has been confirmed are output also from a pulse train separating circuit. This gate signal is used for selecting and outputting the pulse train of the system, which has been confirmed, from the mixture signal and for inhibiting the input of the pulse train, which has been confirmed, to another unit.
