Abstract

Una disposicion incluye una entrada, un circuito de modulacion, un circuito de aislacion, un circuito desmodulador, un circuito detector y al menos dos salidas. La entrada es configurable para recibir una senal de audio y una tension de CC. El circuito de modulacion está configurado para modular la senal de audio y la tension de CC. El circuito de aislacion tiene una entrada aislada eléctricamente de la salida, donde dicha entrada está acoplada al circuito de modulacion. El circuito desmodulador puede operarse acoplado a la salida del circuito de aislacion y está configurado para extraer de allí la senal de audio. El circuito detector puede operarse acoplado a la salida del desmodulador y está configurado para generar una primera senal en respuesta a la deteccion de una senal modulada correspondiente a la tension de CC modulada por el circuito de modulacion.
