WebMar 15, 2016 · Sallen Key low pass filter is considered to have a draw back of low Q. But the Butterworth filter always has Q of 0.7071. Also, equation of Q for Sallen Key has R1, R2, C1, C2 in it. Why then do people say that it suffers from low Q as if it is a problem? Certainly Q becomes very important for band pass and notch filters. \$\endgroup\$ – Web9.2.1.5 Butterworth Low-Pass Filters.
