Abstract

Se proporciona un sistema inalambrico de transmision/recepcion de audio y metodo de uso del mismo. El sistema de transmision/recepcion incluye: un detector de FM para detectar un canal ocupado de entre los canales de radio de FM; un microprocesador para seleccionar un canal de uso que tenga una frecuencia considerablemente distinta al del canal ocupado detectado y, en consecuencia, no interfiera con el mismo; un transmisor de FM incorporado en un sistema de reproduccion de audio para transmitir/recibir una senal de audio en el canal de uso; y un sistema de audio externo para recibir y producir la senal de audio desde el transmisor de FM.
