Low Pass Bessel filter as a Raised Cosine filter

Hello everyone,

I need to design a Raised Cosine Filter with roll-off factor of 0.75 for a Manchester Encoded signal. As of now, I only designed the manchester encoding part, which you can see in the attached figures. I have seen that the Bessel filter has its frequency response similar to a Raised Cosine Filter so, I would like to know where to start! How can I design this filter having to consider the bit duration time for this roll-off factor? Can you tell me some material I could read also? Thanks!
