Abstract
Filtros de central y abonado para multiplexar en frecuencia señal de hilo musical y señal RTB/RDSI. Los filtros de central y abonado para multiplexar en frecuencia señal de hilo musical y señal de RTB/RDSI, están pensados para ser instalados en ambos extremos del bucle de abonado para permitir que llegue señal de hilo musical al abonado de RTB/RDSI, desde la central local digital (2) utilizando para dos transmisiones el par, cumpliendo la triple misión de adicionar la señal de H.M a la de RDSI, proteger a los circuitos de tanto a la central local digital (2) como del equipo receptor de RDSI (5), de la señal de H.M. Figura 1.
