Butterworth polynomial table
http://www.crbond.com/papers/btf2.pdf WebButterworth filters are called maximally flat filters because, for a given order, they have the sharpest roll-off possible without inducing peaking in the Bode plot. 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.
