We want to design the raised-cosine pulse-shaping filter given in (10.138) with ω c = 0.5

We want to design the raised-cosine pulse-shaping filter given in (10.138) with ω c = 0.5 π and β = 0.75 using the Parks–McClellan algorithm. Consider it as a three band filter. Develop appropriate band-edge frequencies and nominal values to design a length L = 41 filter with equal ripple values in each band of 0.01. Provide an amplitude plot to verify your design.
