Abstract

Un dispositivo selector de impulsos para relevar a intensidad grandemente amplificada los impulsos de una onda cortadora modulada por impulsos comprendiendo un circuito oscilador disparador ajustable para el funcionamiento al intervalo normal a un ritmo de impulsión más bajo que le tiempo de impulso más bajo de dicha onda cortadora, un circuito de control para dicho circuito oscilador, medios para aplicar energía de la onda portadora al circuito de control para disparar dicho circuito oscilador durante un intervalo de funcionamiento en respuesta a cada impulso de dicha onda portadora y estando dichos medios de aplicación de energía adaptados para recibir y emitir energía desde dicho circuito oscilador durante el intervalo de funcionamiento del mismo.
