[Discuss-gnuradio] How is interp & decimation in grc taking zero.

[srinivas naga vutukuri]

Hi,


Am using grc, to create a signal source connected to USRP2 sink, and 
from another USRP2 as source and to a scope sink. While setting the 
parameters, i could even set to interp on USRP2 sink and decimation on 
USRP2 source to zero. to see the samples or signal source correctly 
recieving. But when i try using tx_samples.cc and 
rx_streaming_samples.cc, it is not allowing to set to zero (only allowed 
to 4 to 512).
Now my question is the usrp2 is calling the same low level C++ code and 
Why is it so.



best regards,
srinivas.
