Design a phase equalizer for the elliptic filter of Exercise 6.6 with the same order as the filter.

Exercise 6.6

Design highpass Butterworth, Chebyshev, and elliptic filters that satisfy the following specifications:

\[\begin{aligned}A_{\mathrm{p}} & =1.0 \mathrm{~dB} \\A_{\mathrm{r}} & =40 \mathrm{~dB} \\\Omega_{\mathrm{r}} & =5912.5 \mathrm{rad} / \mathrm{s} \\\Omega_{\mathrm{p}} & =7539.8 \mathrm{rad} / \mathrm{s} \\\Omega_{\mathrm{s}} & =50265.5 \mathrm{rad} / \mathrm{s} .\end{aligned}\]
