Hi all,
I am new to gnuradio and i am trying to make simple transmission and
reception.
I want to understand the sampling rate of the uhd sink and source and
how
to choose it
and the sampling rate of the blocks in the flow graph.
when running on sine of 100 kHZ and sampling rate of 0.5 MHz and same
sampling rate for uhd
I get UUUUUUUUUUUUUUUUUUUUUUUUUU ,it means under sampling,Right?
How to avoid it ???
Thanks

Sample rate is really only relevant at the edges, and when calling the
filter synthesis modules, most interior blocks have no concept of
sample rate.
‘U’ means under-run the producer (in this case, your program) can’t keep
up with the consumer–the UHD device.

hi all,
the usrp final samling rate coming out from the codec is 128 Msps so i
think that you should follow this equation : sample rate* interpolation
=128 msps you can set the sampling rate =1 msps and the interpolation
rate =128
try it and inform me of the result
yours,
