The two-pole filter with a damping ratio of 0.707 is the second-order Butterworth filter. Butterworth filters are used in control systems because they do not have peaking. century fc1106fWebDigital Filter Design FIR, IIR, windowing, equiripple, least squares, Butterworth, Chebyshev, elliptic, pulse shaping Design digital filters using as a starting point a set of specifications ( designfilt) or a design algorithm ( butter, fir1 ).
