The present invention is for a high quality digital FM radio system that
utilizes the subcarrier band to generate digital audio signals. The
hybrid FM radio system utilizes the subcarrier band to transmit the
digital FM signals that are synchronized to the analog FM signals. The
receiver processes both the analog and digital signals and a high quality
FM signal results. The receiver may switch between the traditional analog
signal and the higher quality digital signal automatically to present the
best possible audio to the user.
