Thank you, Brian!
Now i know how the interpolation changes, but if bitrate were set, how
are interp/decim rate and
samples-per-symbol derived respectively? Is there a default value for
interpolation rate? Thanks!!!

Hello, everybody!
I am working on the demo file:
gnuradio-examples/python/digital/benchmark_tx.py. In the file
transmit_path.py, it is said “specify bitrate. samples-per-symbol and
interp/decim will be derived.” How are interp/decim rate and
samples-per-symbol derived respectively? what is the range for the variable
interpolation rate? Is interpolation rate increased as a multiple of 4?
could anyone tell me where i can find the dynamical range of interpolation
rate?
Try the wiki:
http://gnuradio.org/trac/wiki/UsrpFPGA#TransmitChain
The interpolating CIC filter, I believe, can handle integers in the
range [4,255]. The source can be found here:
