Abstract

Se describe un sistema de transmision de datos que comprende una fuente de una señal de datos y un modulador, que responde a la señal de datos, que produce una primera señal modulada que representa la señal de datos, y una segunda señal modulada que representa una señal (180) fuera de fase con la señal de datos. La primera y segunda señales moduladas se transportan por medio de un canal de transmision. Un primer desmodulador (50,100) desmodula la primera señal modulada transportada, y un segundo desmodulador (50,100) desmodula la segunda señal desmodulada transportada. Un sustractor (60,70) que responde a los primero y segundo desmoduladores, produce una señal representativa de la señal de datos.
