Abstract
En un receptor superheterodino destinado a recibir selectivamente señales moduladas en amplitud o señales moduladas en frecuencia un amplificador de doble finalidad con la combinación de un dispositivo de descarga electrónica que tiene un ánodo un cátodo un electrodo de control y un electrodo pantalla un primer circuito de entrada para aplicar una onda de señal de frecuencia relativamente baja a dicho electrodo de control medios para derivar de dicho ánodo dicha onda de señal de baja frecuencia en forma amplificada un segundo circuito de entrada para aplicar una onda de señal de frecuencia relativamente alta a dicho cátodo medios para derivar de dicho electrodo-pantalla dicha onda de señal de alta frecuencia en forma amplificada y medios de distribución para incapacitar selectivamente dicho primer circuito de entrada o dicho segundo circuito de entrada.In a superheterodyne receiver designed to selectively receive amplitude modulated signals or frequency modulated signals a dual-purpose amplifier with the combination of an electronic discharge device having an anode, a cathode, a control electrode and a screen electrode, a first input circuit for applying a relatively low frequency signal wave to said control electrode means for deriving said low frequency signal wave from said anode in amplified form a second input circuit for applying a relatively high frequency signal wave to said cathode means for deriving from said shield electrode said high frequency signal wave in amplified form and distribution means for selectively disabling said first input circuit or said second input circuit.
