WebNote that, with practical filters, the frequency ω 0 does not exist. There is no specific frequency where the magnitude responses changes from a flat, horizontal one to a decreasing one. Typically, ω 0 is chosen as the frequency at which the magnitude response of the filter reaches -3 dB. For example, the simplest first order Butterworth ... WebYou can approximate the filter response with a large FIR filter and convolution, which can be moved into frequency domain to solve phase problems, but it's not truly Butterworth if you do that.
