WebButterworth Filters (3) We are only interested in H(s), not H(-s). Therefore the poles of the low-pass filter are those lying on the Left-Hand Plane (LHP) only, i.e. The transfer function of this filter is: This is a class of filter known as Butterworth filters. E2.5 Signals & Linear Systems Lecture 9 Slide 14 Butterworth Filters (4) WebAccording to the literature, Butterworth filters of order 4 are suitable. Here is a couple of codes for high-pass, low-pass, and notch filter design using 4th-order Butterworth filter ...
