WebThe design of analogue filters other than low-pass is based on frequency transformations, which produce an equivalent high-pass, band-pass, or band-stop filter from a prototype low-pass filter of the same class. The analogue IIR filter is then converted into a similar digital filter using a relevant transformation method.
