Butterworth filter design - MATLAB butter - MathWorks

WebAlthough IIR filters have nonlinear phase, data processing within MATLAB is commonly performed "off-line," that is, the entire data sequence is available prior to filtering. This allows for a noncausal, zero-phase filtering approach (via the filtfilt function), which eliminates the nonlinear phase distortion of an IIR filter. WebCopy Command. This example shows how to design classic IIR filters. The initial focus is on the situation for which the critical design parameter is the cutoff frequency at which the filter's power decays to half (-3 dB) the nominal passband value. The example illustrates how easy it is to replace a Butterworth design with either a Chebyshev or ...
