Repeat Prob. 8.1-12 using α_p
= 0.5 dB and α_s
= 40 dB. Using a cascade of secondorder sections, show a realization of this filter.

Prob. 8.1-12

Using the bilinear transform with prewarping, design a digital lowpass Butterworth filter that satisfies αp = 2 dB, α_s
= 11 dB, ω_p
= 100π rad/s, and ω_s
= 200π rad/s. The highest significant frequency is 250 Hz. If possible, it is desirable to oversatisfy the requirement of α_s.
