Although almost all analog electronic filters are IIR, digital filters may be either IIR or FIR. The presence of feedback in the topology of a discrete-time filter (such as the block diagram shown below) generally creates an IIR response. The z domain transfer function of an IIR filter contains a non-trivial denominator, describing those feedback terms. The transfer function of an FIR filter, on the other hand, has only a numerator as expressed in the general form derived below.

WebButterworth filter是工程中较为常用的FIR滤波器之一，相比FIR滤波器，虽然其相位特性要差一些，但是其可以通过较低的阶数来实现高阶FIR才能达到的滤波效果。和其他几种常用的IIR滤波器相比，其带内波纹比较平缓，且阻带逐渐衰减到0，对比图如下所示： Web11 mei 2014 · Wn : array_like. A scalar or length-2 sequence giving the critical frequencies. For a Butterworth filter, this is the point at which the gain drops to 1/sqrt (2) that of the passband (the “-3 dB point”). For digital filters, Wn is normalized from 0 to 1, where 1 is the Nyquist frequency, pi radians/sample. ( Wn is thus in half-cycles / sample.)
