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.
