Abstract

La presente invención se refiere a el aparato para regular digitalmente la magnitud de una señal de salida derivada de una señal de entrada, caracterizado por: un elemento para generar una corriente de impulsos con un ciclo de servicio controlable; un elemento para controlar el ciclo de servicio de los impulsos; un elemento para suministrar la corriente generada de los impulsos variables del ciclo de servicio; un elemento para filtrar la corriente de impulso variables del ciclo de servicio a fin de desarrollar una señal de referencia, la magnitud de la señal de referencia responde y es proporcional al ciclo de servicio de la corriente de impulsos; un elemento no lineal de dos terminales que tiene un valor de resistencia que varía de acuerdo con la corriente que pasa a través del elemento; una fuente de señales de entrada para suministrar una señal de entrada; un elemento que responde a la magnitud de señal de referencia para variar la resistencia de funcionamiento instantánea del elemento no lineal de dos terminales; y un medio amplificador con una ganancia variable para amplificar una señal de entrada desde la fuente de señales, la ganancia del circuito de amplificación responde a la resistencia de funcionamiento instantánea no lineal de dos terminales.
