Abstract: Disclosed is a frequency amplitude modulation (FAM) transmission apparatus and method by combining a frequency modulation (FM) signal and a digital modulated amplitude modulation (AM) signal. A FAM transmission method includes receiving an FM signal created by modulating an audio signal that includes audio information for mono or stereo broadcasting based on an FM scheme; receiving a digital pulse created by modulating digital data used to provide an additional service for the mono or stereo broadcasting based on an amplitude modulation (AM) affiliated digital modulation scheme; creating an AM signal by by adjusting the digital pulse to have a value greater than 0; and creating a FAM signal by combining the FM signal and the AM signal.
