Abstract

EN UN CIRCUITO SE DESCRIBE INTERFERENCIA DE INDICACION DE DERIVACION DE SEÑAL 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 UTILIZABLE DE LA SEÑAL MULTIPLEX ESTEREO. LA SEÑAL MULTIPLEX ESTEREO RECIBIDA SE TOMA POR MEDIO DE UN FILTRO PASA BAJO, TANTO LA SEÑAL FILTRADA PASA BAJO COMO LA SEÑAL MULTIPLEX ESTEREO RECIBIDA SON SOMETIDAS AMBAS 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. AMBAS SEÑALES MULTIPLEX ESTEREO EN LA SEGUNDA RELACION DE EXPLORACION SON SUBSTRAIDAS UNA CON RESPECTO A OTRA.
