For less than 10% error from operational amplifier,

((QO fO)/BW) < 0.1 where fo and BW are expressed in Hz.

If source impedance varies, filter may be preceded with

voltage follower buffer to stabilize filter parameters.

Given: fo = center frequency

A(fo) = gain at center frequency

Choose value fo, C
