Abstract
Una disposición de circuito para un detector de caídas de señal, para detectar "caídas" (interrupciones o debilitamientos bruscos) durante la reproducción de señales (en particular, señales de video) que están almacenada en un portador de registro, disposición a la cual se aplica la señal explorada, como modulación de fase, y que en su circuito o camino de señal incluye un amplificador para amplificar la señal sin caídas, a un primer nivel de señal concreto y específico, y un dispositivo de umbral para detectar si la señal decae por bajo de un segundo nivel de señal que corresponde al nivel de umbral, y que suministra una señal de conmutación en dependencia de la activación del dispositivo de umbral, caracterizada dicha disposición por el hecho de preverse un dispositivo de control, cuya entrada va conectada al circuito de señal antes o delante del dispositivo de umbral y que, según la amplitud de la señal sin caída, suministra una cantidad de control por medio de la cual la magnitud de ladiferencia de nivel entre los niveles de señal primero y segundo se mantiene dentro de un intervalo específico, y de preferencia a un valor constante dentro de dicho intervalo.
