Abstract
SE MUESTRA UN SISTEMA DE TRANSMISION PARA LA TRANSMISION INSENSIBLE DE POLARIZACION DE SEÑALES EN UNA RUTA DE SEÑAL (ST) ENTRE UN PRIMER PUNTO DE CONEXION DEL SISTEMA (S1) PARA UN TRANSMISOR (T) Y UN SEGUNDO PUNTO DE CONEXION DEL SISTEMA (S3) PARA UN RECEPTOR (R), Y ENTRE DOS PUNTOS DE CONEXION DEL SISTEMA ADICIONALES (S2 Y S4) PARA UN TRASMISOR Y RECEPTOR ADICIONALES. EN UN LADO SE DISPONE EL RETARDADOR DE ORDEN SUPERIOR (HR) ENTRE LOS PUNTOS DE CONEXION DEL SISTEMA Y LA RUTA DE SEÑAL (ST). EL SISTEMA COMPRENDE UN CIRCUITO HIBRIDO PRIMERO Y SEGUNDO (H1,H2), CADA UNO CON DOS PUNTOS DE CONEXION UNIDIRECCIONALES Y UN PUNTO DE CONEXION BIDIRECCIONAL. LOS PUNTOS DE CONEXION UNIDIRECCIONALES FORMAN LOS PUNTOS DE CONEXION DEL SISTEMA (S1 A S4 INCLUSIVE). EL PUNTO DE CONEXION BIDIRECCIONAL DE UNO DE LOS CIRCUITOS HIBRIDOS (H1) ESTA CONECTADO A TRAVES DEL RETARDADOR DE ORDEN SUPERIOR (HR), Y EL PUNTO DE CONEXION BIDIRECCIONAL DEL OTRO CIRCUITO HIBRIDO (H2) ESTA CONECTADO DIRECTAMENTE A LA RUTA DE SEÑAL (ST).
