Spindle parameters
This parameter is only taken into account for the "anti-resonance (notch)" filter type.
It is calculated with the following formula.
Points f1 and f2 correspond to the cutoff frequency or frequency at which its amplitude drops 3 dB
or reaches 70% of the nominal amplitude.
SHARE (P71)
percentage of signal going through the filter. This value must be equivalent to the percentage
overshooting of the resonance because it has to make up for it.
This parameter is only taken into account for the "anti-resonance (notch)" filter type.
