Abstract

Una disposición para indicar, dentro de un tren de impulsos entrante, solamente impulsos de señal que tienen una longitud superior a un valor límite, que comprende circuitos lógicos con el fin de generar un tren de impulsos de control por medio del tren de impulsos entrante, y tratar los valores lógicos en dicho tren de impulsos de control y dicho tren de impulsos entrante, caracterizada por un elemento monoestable con el fin de iniciar, por medio de cada flanco anterior del tren de impulsos entrante, la generación de un impulso de control que finaliza a lo sumo en un instante determinado por dicho valor límite, un elemento de interrupción con el fin de interrumpir el impulso de control respectivo, por medio del flanco posterior respectivo de un impulso perturbador entrante cuya longitud es inferior a dicho valor límite, y circuitos de evaluación para generar señales de indicación por medio de los impulsos de control no interrumpidos, cuyas señales de indicación indican cada una un impulsode señal entrante.
