Hello List,
I have a short question about the decimation rate of the
USRP N210 :
Since I know that the decimation rate of the N-Series is
supposed to be programmable and that one was able to
change it using the usrp_rx_cfile.py-script, why is this
option missing in the UHD-Version of this
I tried almost all things. I also tried without -s.
Well, the current situation is I am getting the three kinds of IQ data.
1. both of the IQ valid signal is achieved.
2. Either I or Q is valid, the other one is a dead signal (showing '0',
zero values)
3. Both of them are dead signal ('0' values).

Hello Leech,
Why do you not think that zero is valid?
These I/Q signals are voltage-samples of sinusoidal functions, which
cross zero.
Would you please explain this in a little bit more detail.
In fact I need some strong reason that zero values can be used as value
i.e. the signal is not dead.
Hi again
Thank you very much, we expect our thesis will be available from some time
next year, we will add it to the academic section.
The work we have done so far have pointed us to the daughterboard mixer.
All mixers have problems causing harmonics, and our research so far has
shown us that
Forgot the list :)
The quick answer is:
It's done for you
the formula is:
decimationrate = iround(tick_rate/sample_rate);
where tick_rate = 100e6, and sample_rate is the sample rate you set.
It will only allow accurate matches of the decimation rate, otherwise it
will tell you what sample rate

Actually, I am not using any sinusoidal function in this measurement.
So, zero values are not valid I think. I am mostly using the noise
signal so I thought there must be a value.
Here is a sample of what I got.
Any idea would be highly appreciated.

Hi list,
I want to send two signal which at different frequency. Can I simply add
these two signals' sample to generate a new signal
which mix the two signal?
Regards!
