can we receive regular AM broadcast transmission with a DRM receiver? or DRM has its separate broadcast?... I am unable to understand it...kindly help

Digital Radio Mondiale (DRM) use COFDM modulation. To receive standard AM have to demodulate the signal before the digital demodulator. Some superheterodyne receivers convert the last IF in a very low one (12kHz) and feed direct the BB processor. In this case an option to demodulate standard AM signals is to pick-up the signal from the previous IF, amplify and demodulate.
