Patent ID: 7127008

Claim:
A method of processing an AM radio signal comprising the steps of: receiving an AM radio signal including an upper sideband portion and a lower sideband portion; passing the upper sideband portion and the lower sideband portion through a plurality of bandpass filters to produce a plurality of filtered signals; demodulating the plurality of filtered signals to produce a demodulated upper sideband signal and a demodulated lower sideband signal; weighting the demodulated upper sideband signal and the demodulated lower sideband signal using a weighting factor that varies in response to signal to noise ratio in the demodulated upper sideband signal and the demodulated lower sideband signal to produce a weighted demodulated upper sideband signal and a weighted demodulated lower sideband signal; and combining the weighted demodulated upper sideband signal and the weighted demodulated lower sideband signal to produce an output signal.
