Goal is to design a 4th - order iir butterworth bpf with center frequency 100 hz and bandwidth 40 hz. 1.choose an appropriate sampling rate (e. g., 300 hz) and determine the sample period.2.pre-warp the center, lower, and upper cutoff frequencies using, νννν=2ννtan(νν2νν)3.create a normalized analog 4th-order butterworth lpf (normalized filter will have cutoff of 1 rad/sec), and apply lp to bp transform, using the prewrapped frequencies in step 3. 4.apply bilinear transform to create a digital filter, ν»ν»(ν§ν§). 5.plot frequency response of both bpfs,ν»ν»(ν ν ) and ν»ν»(ν§ν§).
