Given: Pass band attenuation: $-2 \mathrm{dB}$jm
Gain at Pass-band edge $: A_{p}=10^{-2 / 20}=0.7943 $
Stop band attenuation $: \geq-10 \mathrm{dB}$
Gain at Stop-band edge $:A_{s}=10^{-10 / 20}=0.3162$
Step 1: Pre-warp Analog Frequency
Since the given frequencies are in rad/sec, they must be Pre-warp analog frequencies
Pass-band edge $\Omega_{p}=20$
Stop-band …
