    What center frequency?
    What Q? (width of notch)?

    The calculator on your linked page avoids having to understand the transfer function...

    Notch of 50hz
    A q high enough so that the 3rd harmonic(150hz) is not effected any. So around 8 or so.

    I want to use it to see only 3rd harmonic distortion...I'd like to attenuate the notch freq as much as possible, no less then -80db but preferably 100db
