Abstract

Perfeccionamientos en sistemas de objetos móviles, caracterizados por un circuito desmodulador cuya salida es una tensión alterna de amplitud y frecuencia dependientes de la amplitud y frecuencia de dos señales de entrada y que comprende un circuito resonante en paralelo constituido por un inductor y dos condensadores, el punto medio de estos está unido a tierra mientras que cada extremo de dicho circuito resonante paralelo está conectado a dicha unión con tierra mediante un inductor de choque o restricción de la radiofrecuencia respectiva y ajustado para resonar a la misma frecuencia de una de las señales de entrada que se aplica al mencionado circuito paralelo, por medio de un capacitador o condensador de acoplamiento, un par de rectificadores dispuestos de tal modo que un polo de uno de ellos y el polo distinto del otro están conectados respectivamente mediante una resistencia,a punto común al que se aplica, por un condensador de acoplamiento la segunda de las señales de entrada mencionada, el otro polo del rectificador mencionado está conectado, a través de una resistencia al punto de unión entre dicho inductor y uno de los conductores indicados del circuito resonante paralelo y el otro polo del otro rectificador mencionado está conectado, a través de una resistencia, al punto de unión entre dicho inductor y el segundo de los capacitores o condensadores indicados del circuito resonante en paralelo y una red de impedancia conectada entre dicho punto común y la mencionada unión a tierra y desde un punto de la cual se obtiene la salida del circuito desmodulador mencionado.
