Abstract

EN UN CIRCUITO PARA LA DERIVACION DE UNA SEÑAL INDICANDO INTERFERENCIA EN UNA SEÑAL MULTIPLEX ESTEREO RECIBIDA, EN DONDE LA SEÑAL MULTIPLEX ESTEREO SE ENCUENTRA EN LA FORMA DE UNA SEÑAL DIGITAL CON UNA PRIMERA RELACION DE EXPLORACION QUE ES SUSTANCIALMENTE MAYOR QUE DOS VECES EL LIMITE SUPERIOR DEL CAMPO DE FRECUENCIA UTILIZADO DE LA SEÑAL MULTIPLEX ESTEREO, LA SEÑAL MULTIPLEX ESTEREO RECIBIDA SE TOMA POR MEDIO DE UN FILTRO PASO ALTO. LA SEÑAL MULTIPLEX ESTEREO FILTRADA PASO ALTO SE SOMETE A DECIMACION A UNA SEGUNDA RELACION DE EXPLORACION QUE ES MAYOR QUE DOS VECES EL LIMITE SUPERIOR DEL ALCANCE DE FRECUENCIA UTILIZADO DE LA SEÑAL MULTIPLEX ESTEREO.
