Thanks, good to know.
To clarify, I was just wondering if I should expect the filter to be apparent in the FFT results, because previous discussions of the notch filter implied that they should be. I wasn’t experiencing any adverse effects from applying the filter, although I agree my settings are a bit crazy, but that’s just because I was trying to see some results. Also, the filter settings I have should do 100-150 Hz rather than 75-175; the INS_NOTCH_BW parameter (should) set the total bandwidth, with _FREQ as its center. I assume so, anyways, based on the description. Guess I’ll check the code to be sure.
