"WebTo achieve a digital filter cut-off frequency of f c, the analog prototype cut-off frequency must be: F c = f s π tan( πf c f s) F c = f s π t a n ( π f c f s) This exercise is called frequency pre-warping. For example, if f s = 100 Hz and we want f c = 20 Hz, then F c = 23.13 Hz. 3. Scale the s-plane poles by 2πF c. " - Iir notch filter design
