Abstract
Perfeccionamientos generadores de alta seguridad para instalaciones de tratamiento de la información, constituida por tres generadores idénticos que comprenden cada uno un oscilador, un comparador de fase, un circuito de elaboración de señal que comprende un circuito mayoritario, un divisor de frecuencia alterna gobernado por un primer circuito mayoritario, recibiendo los circuitos mayoritarios, cada uno, una señal de base de cada oscilador, caracterizados porque en cada generador, el comparador de fase recibe una señal de base del oscilador del generador, una señal de base y una señal de base inversa de cada uno de los otros dos generadores, porque el circuito de elaboración de señal comprende además un filtro, un inversor y un amplificador diferencial que polariza la salida del inversor, el cual suministra una señal de salida del gobernador, y porque el divisor de frecuencia interna recibe a la entrada y a través de un inversor, la señal de salida del gobernador, conectándose su salida, por una parte, al primer circuito mayoritario y a un circuito de subordinación externa cuya salida se conecta a una entrada de control del oscilador y, por otra parte, a tres inversores que proporcionan cada uno una señal de sincronización, recibiendo el primer circuito mayoritario una señal de sincronización inversa de cada uno de los otros dos generadores.
