5-2-5 Notch filter
In case of a low machine stiffness, you cannot set up a higher gain because vibration and noise occur due to oscillation
caused by axis distortion or other causes. By suppressing the resonance peak at the notch filter, higher gain can be
obtained or the level of vibration can be lowered.
