A method of receiving an FM digital audio broadcasting signal including a
first plurality of subcarriers in an upper sideband of a radio channel
and a second plurality of subcarriers in a lower sideband of the radio
channel comprises the steps of mixing the digital audio broadcasting
signal with a local oscillator signal to produce an intermediate
frequency signal, passing the intermediate frequency signal through a
bandpass filter to produce a filtered signal, determining if one of the
upper and lower sidebands of the digital audio broadcasting signal is
corrupted, and adjusting the local frequency oscillator signal to change
the frequency of the intermediate frequency signal such that the bandpass
filter removes the subcarriers in the upper or lower sideband that has
been corrupted. A receiver that processes a digital audio broadcasting
signal in accordance with the method is also provided.
