Abstract

SISTEMA DESCODIFICADOR MEJORADO DE SEÑALES DE CODIGO Y SISTEMA FILTRANTE DE SEÑALES DE ENTRADA PARA SEÑALIZACION DE FERROCARRILES, EN DONDE EL SISTEMA DESCODIFICADOR COMPRENDE UN CAPTADOR DE SALIDAS DE CORRELACION DE DICHAS SEÑALES DE CODIGO CON SEÑALES DE REFERENCIA EN CUADRATURA DE FASE MUTUA, UN SUMADOR DE LAS SALIDAS DE CORRELACION, DANDO UNA SALIDA CONSTANTE CUANDO ESTA PRESENTE DICHA SEÑAL DE CODIGO, Y MEDIOS PARA DERIVAR UNA SEÑAL DE CONTROL DE DICHA SALIDA DEL SUMADOR. EL SISTEMA FILTRANTE INCLUYE MEDIOS PARA OBTENER SALIDAS DE CORRELACION DE DICHAS SEÑALES DE ENTRADA CON SEÑALES DE REFERENCIA EN CUADRATURA DE FASE MUTUA Y UN SUMADOR DE LAS SALIDAS DE CORRELACION PARA DAR UNA SALIDA REPRESENTATIVA DE DICHAS SEÑALES DE ENTRADA CUANDO ESTAN DENTRO DE CIERTA BANDA DE FRECUENCIAS. EL INVENTO ES UTIL EN RELACION CON LOS CIRCUITOS DE TRANSMISION DE SEÑALES DE CODIGO INSTALADOS EN VIAS FERREAS.
