Abstract

La presente divulgación se relaciona con un método para decodificar una señal de AM y FM combinada, qie comprende los siguientes etapas: combinar dicha señal óptica codificada con la luz de un oscilador local configurado con una frecuencia de oscilador local; convertir la combinación del oscilador local y señal óptica codificada en una o más señales eléctricas por medio de al menos un convertidor optoeléctrico que tiene un ancho de banda de frecuencia predeterminado, de tal manera ofreciendo una señal eléctrica amplificada y codificada con una o más corrientes de señal, donde un tipo de estados tienen una frecuencia de oscilación más alta que otro tipo de estados; rectificar la(s) corriente(s) de señal codificada, así logrando un espectro energético, en donde dicho espectro energético tiene diferentes estados, tales como estados "0" y estados "1", con diferentes niveles energéticos para poderlos distinguir, dicha frecuencia de oscilador local se define por un desfase positivo de frecuencia de dicho oscilador local de la frecuencia de uno de los estados en dicha señal óptica codificada, y dicho desfase de frecuencia del oscilador local se ajusta para depender de dicho ancho de banda de frecuencia.
