You are presumably discussing a *specific* signal flow when you talk
about bit-rate. GRC doesn't, inherently, know anything about
Thank you for replying me. I am trying to simulate like this:
File Source -> packet to Unpacket -> chunk to symbol ->
The parameter in chun to symbol is [0,1], which means it will
transmit a pluse to represent 1 and transmit nothing to represent
0. But my question is that how to control the speed of this data
flow. Right now the speed is default 500K/s.
Thank you for your time and help.
The UHD sink has a sample rate parameter. Your whole graph will be
"paced" by that parameter. Make it whatever you want, subject to
the usual restrictions that it must be a proper decimated rate
from the basic sample rate.
What device are you using?
For N2XX, the basic rate is 100e6 so sample rates have to be a
proper integer fraction of that rate
For B100/E100/USRP1 the basic rate is 64e6
