Notch Filter
The notch filter is a sort of band stop filter that eliminates specific frequency components. You can use
a notch filter to eliminate resonant frequency components of an apparatus, which allows vibration
avoidance and higher gain setting.
This drive provides notch filters in 4 levels, and you can set frequency, width, and depth for each filter.
You can use one or two notch filters as adaptive filters, which set the frequency and width automatically
through real-time frequency analysis (FFT).
