Abstract

Una disposición para seleccionar un tren de impulsos eléctricos cortos que tienen una frecuencia de repetición dada, de otras señales y/o ruidos que lo acompañan, que comprende un multivibrador estabilizado adaptado para generar impulsos de paso que tienen una frecuencia de repetición próxima a la frecuencia de repetición dada, una válvula de paso normalmente en condición bloqueada, medios para aplicar señales entrantes a dicha válvula de paso, medios para aplicar dichos impulsos de paso para desbloquearla en cada impulso y medios que conectan la salida de dicha válvula de paso a dicho multivibrador, a fin de sincronizarlo.An arrangement for selecting a train of short electrical pulses having a given repetition frequency, from other accompanying signals and / or noises, comprising a stabilized multivibrator adapted to generate step pulses having a repetition frequency close to the frequency of given repetition, a bypass valve normally in a blocked condition, means for applying incoming signals to said bypass valve, means for applying said bypass pulses to unblock it at each pulse and means connecting the output of said bypass valve to said multivibrator , in order to synchronize it.
