Nth order Butterworth filter transfer function for a given roll-off frequency
The given set of functions is normalized to wc=1rad/sec. That means:  The frequency variables in all expressions are to be interpreted as S=s/wc (capital letter S).

Therefore, you have nothing to do than to select different cut-off frequencies wc and to rescale the variable. Example: For wc=10rad/ses you must set S=s/10.
