Weba. For a third-order low-pass Butterworth filter, the phase shift at the cutoff frequency (fc) is -90 degrees. The phase shift will increase by -180 degrees for every octave above the cutoff frequency. At frequencies much greater than the cutoff frequency (f >>> fc), the phase shift will approach -270 degrees. WebThese four pieces of known information must be used to compute filter order n, 3dB cut …
