The gain stage is operably coupled to adjust gain of the input signals to produce gained input signals. The subtraction module is operably coupled to subtract the first low pass filtered signals from the gain input signals to produce first stage signals. The second low pass filter stage is operably coupled to filter the first stage signals to produce channel selected signals.
