The frequency response charts shown … WebDiscretization of a Fourth-Order Butterworth Filter. This is an example on how to design a filter in the analog domain, and then use the bilinear transform to transform it to the digital domain, while preserving the cut-off frequency. We'll be using formulas derived on the Bilinear Transform and Butterworth Filters pages.
