Not sure what your question is. Signal amplitudes are usually in Volts,
that's just the right physical unit.
I assume you're asking because in the di

Hi,
I removed the old version of the GNURadio installed on the USRP e110,I
followed instructions on the FAQ forum in order to install a new version of
it.everything seemed all right at the beginning but suddenly an error came
out of no where:
[ 49%] Built target _filter_swig_swig_tag
[ 49%] Build
Abouda,
I've seen the "g++: Internal error: Killed (program cc1plus)" error before
when I ran out of memory. Try creating more swap space and use "make -j1"
to reduce the number of threads used for the compile.

hi ,Martin Braun
well ,in my impression, the unit of is noisy is dB,so i feel fuzzy about the
volt,
thanks for your reply!

Hi 猪猪头,
you've replied to the wrong thread; however:
dB is *always* a relative measure. You can't output dB; it always has
to be dB in relation to something.
The parameter of the noise source is amplitude.
Like Martin, if I *want* to stick a phy

Hi again,
so, the exception appeared again. Just to remind:

I can't find what (65) means.
This time complete block of code was encapsulated by try and except but
nothing was caught.
Here is my code:

I was trying to install gr-ieee802.15.4
Before everything was ok then once I got this error at CMake:

The '(65)' looks to be the line number where the error occured. Notice
that previously the line number was '(62)' which probably means that the
error is coming from line 65 of one of the files you have been editing.

It's commented line inside the function called only once inside
constructor, and never again :)

Hi Nemanja,
Simple explanation:
You haven't fixed your syntax for the first except clause.
Going back to my other post, it should read
"except mdb.Error as e:", not "except mdb.Error, e".
Because you didn't do that, "e" is undefined in your except cl

Ali,
FYI, I've CC'd the discuss-gnuradio@gnu.org mailing list to encourage
feedback.
I'd recommend starting by creating a basic flowgraph in GRC
(gnuradio-companion), run it and then rename the created python file. The
rename must be done before editing it otherwise it will get overwritten.

Mostly people use complex baseband samples. In C++ code in GR their
data type is gr_complex which is a wrapper for std::complex.

Right. We've discussed this on several dev calls, not sure if here on

In this scenario would the message passing interface be the best input type?

Hi,GR
I run Bloessl's "802.11 OFDM physical layer" GRC program.
The input and output block are "Pad source" block.
What is the funcion of "Pad source",how to use "Pad source"?
If I want to use "File source" block to be the data input and output,how can I
connect "File source" with the system?
Thank you nathan！
