Abstract

Procedimiento de restitución de una información por diferenciación de los tamaños de intervalo y dispositivo resultante de la ejecución de tal procedimiento, cuyos intervalos son de una primera pluralidad m de intervalos diferentes representativos de la distancia que separados impulsos consecutivos de una señal impulsional cada uno de cuyos impulsos tiene una anchura mínima predeterminada 1, del tipo que comprende la formación de una segunda pluralidad n de señales separadas que comprenden dicha señal impulsional y versiones retardadas de manera diferente en una distancia e entre ellas de dicha señal impulsional, y la comparación entre ellas de dicha señal impulsional, y la comparación entre ellas de dichas señales para producir una señal de salida representativa de dicha información, caracterizado e entre una primera y una segunda señal de dicha segunda pluralidad n de manera que sea definido un primer intervalo a de dicha primera pluralidad m cuando cae un frente acescente un primer impulso de dicha segunda señal en un primer impulso de dicha primera señal y que sea definido un segundo intervalo b de dicha primera pluralidad m cuando cae un frente descendente de un segundo impulso de dicha segunda señal en un segundo impuso de dicha primera señal, de tal modo que la ausencia de un frente de un impulso de la segunda señal en un impulso de la primera señal corresponda a un inervalo de la pluralidad m que es diferente de dichos primero y segundo intervalos, y porque el numero n es determinado por el numero de los retardados así establecidos e, necesarios para agotar dicha pluralidad m de intervalos.
