Abstract

EN UN RECEPTOR DE RADIO CON UN CIRCUITO DE ENTRADA, AL QUE SE GUIA LA SEÑAL DE ENTRADA, CON UN MEZCLADOR PARA LA DERIVACION DE UNA SEÑAL ZF Y CON UN FILTRO ZF, CUYA ZONA DE PASO CORRESPONDE A UNA ZONA DE FRECUENCIA DE UTILIZACION DE LA SEÑAL DE RECEPCION, SE MODULAN EN AMPLITUD LAS SEÑALES RECIBIDAS CON UNA SEÑAL AUXILIAR PARA EL RECONOCIMIENTO DE LA INTERMODULACION, CON LO CUAL SE GENERA BANDAS GENERALES QUE SE ENCUENTRAN FUERA DE LA ZONA DE FRECUENCIA DE UTILIZACION. LAS AMPLITUDES SE COMPARAN A TRAVES DE UNA BANDA LATERAL QUE SE ORIGINA MEDIANTE LA MODULACION CON LA SEÑAL AUXILIAR Y EL PORTADOR RECIBIDO EN LA SEÑAL ZF. MEDIANTE DESVIACIONES DE LA RELACION SERVIDA A TRAVES DEL GRADO DE MODULACION EN MODULACION CON LA SEÑAL AUXILIAR SE DERIVAN LAS SEÑALES EXISTENTES DE INTERMODULACION DE LA SEÑAL RESPECTIVA.
