ABSTRACT:
A method and apparatus are described which reduce the presence of an unwanted signal. According to one embodiment, a first signal is provided from a desired location that includes an unwanted signal while a second signal is provided from an alternate location (e.g., one where the unwanted signal is less of a proportion of the total signal). The first and alternate signals are provided to respective signal processors. A level for a selected frequency band of the first and alternate signals is adjusted so that an increase in one results in a decrease in the other. Doing so allows the frequncy band that includes the unwanted signal to be reduced in the desired first signal and filled in with a similar frequency band from the alternate signal.
