Notch Filter
Notch filter is a sort of band stop filter to eliminate specific frequency component. You can use a notch
filter to eliminate the resonant frequency component of an apparatus, resulting in avoiding vibration
while setting a higher gain.
This drive provides notch filters with 4 steps in total, and you can set the frequency, width, and depth
for each filter. You can use one or two notch filters as adaptive filter, setting the frequency and the width
automatically through real-time frequency analysis (FFT).
