WebUsing the formula, we get a Q-factor of 0.144. Since the stopband is very wide, the difference between f 2 and f 1 is large. Therefore, the denominator is relatively large, making for a small Q-factor. So the quality factor again for a notch filter is the difference between the -3dB cutoff frequencies over the null frequency. WebWhen using >2nd order Butterworth all breakpoints and Q’s are staggered to align the -3dB point and spread out eack pole on the semi-circular poles of this filter. but as I answered Av=11 * 100 kHz is not the GBW required, it must be multiplied by the max Q^2 as a minimum or 100 x.
