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, 휔휔푝푝=2푇푇tan(푇푇2휔휔)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, 퐻퐻(푧푧). 5.plot frequency response of both bpfs,퐻퐻(푠푠) and 퐻퐻(푧푧).
