The BWs are 20mhz, 40mhz and 80Mhz respectively. The host can range from a server with 48 cores(2.6Ghz), 256GB ram to a laptop with 8 cores(3.0Ghz), 64GB ram.

I am aware of the Fractional Resampler and the Rational Resampler. Is one better than other, take less CPU cycles, etc.? Is there a different block which would suit my needs more efficiently? Should I instead look to implement the resampling within C++ as opposed to adding another block to my flowgraph? I am going to do the above with the following rates: 46Msps -> 50Msps, 92Msps -> 100Msps. How much of your bandwidth are you actually looking to keep intact? How fast is your host CPU? Brian
