Butterworth Filter Design, Equations and Calculations

The Butterworth filter design can be implemented digitally based on two methods matched z-transform and bilinear transform. An analog filter design can be descritized using these two methods. If we consider Butterworth filter which has all-pole filters, then both the methods impulse variance and matched z-transform are said to be equivalent.
