An AM-FM hybrid signal is created which may be used to communicate simultaneously with both RFID tags that receive AM signals and wireless devices that receive FM or PM signals. The AM-FM hybrid signal may be fed back into the system's receiver at the local oscillator in order to recover the RFID tag's FM response, thus enabling simultaneous reception and decoding of both RFID tag FM response and FM wireless device response.
