Hello,
I am receiving data from a radio at 23Msps, and I would like to resample to a rate of 25Msps in which my software program can ingest it. 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?
