WebIt is also worth noting that the maximum amplitude, the minimum loss for the Butterworth filter response, occurs at 0 Hz or radians/s. When plotted on logarithmic scales, the Butterworth filter response is flat within its pass-band and then rolls off with an ultimate linear roll off rate of -6 dB per octave (-20 dB per decade). A second-order ... Webfor designing Butterworth (and other types of) filters. For example, the code N = 3; W = 1; [num,den] = butter(N,W,’s’) will design the 3rd-order Butterworth filter that is discussed in the previous example. N is the filter order.
