Abstract

Perfeccionamientos en amplificadores selectivos, destinados a seleccionar una señal deseada entre señales indeseables, caracterizándose por comprender un circuito de cátodo condicionado, cuya entrada se alimenta por las señales a seleccionar y cuya salida se conecta a la entrada de un circuito en puente, cuya salida está conectada a la entrada de un circuito diferencial de amplificación que proporciona la señal seleccionada; el circuito en puente está preparado de modo que se encuentra en un estado de equilibrio para las frecuencias de las señales indeseables y en un estado de desequilibrio máximo para la frecuencia de la señal deseada.
