WebThe commonly used analog filters are 1. Butterworth filters – no ripples at all, 2. Chebychev filters - ripples in the passband OR in the stopband, and 3. Elliptical filters - ripples in BOTH the pass and stop bands. The design of these filters are well documented in the literature. A disadvantage of IIR filters is that they usually have ...
