Three of the common filter topologies are Chebyshev, Butterworth, and Bessel. Which filter topology has the flatest response in the passband? Which filter topology has the steepest decline into the ...
The Chebyshev filter features a steep roll-off, but has ripple in the pass band, so it is not suited for audio signal use, where a flat response is ideal. The roll off is so fast that the common ...
