Yes, that's right.

hi community,
i tried using the examples provided in gr-digital/examples/ofdm. when i use
them i couldn't able to get the peaks at the output of Schmidl&cox block
but if i change the tx_ofdm.grc in such a way that only payload then i can
able to detect the peaks. i tried using the logging from ofd
Let's cover some signal processing basics:
Say our block's input signal is x[k] and the output signal is y[k].
Let's assume there's one input to keep things simple.
If a block has a history of N, the output depends on N samples of the
input, or
y[k] = f(x[k], x[k-1], ..., x[k-N-1]).
If the block
Hi all guys again,
I wonder if somebody was implementing signal source that is able to read
multyple files from specified folder?
If not, i would like to hear ur opinion about that idea and maybe
suggestions, cause I will probably try to implement something like that.
Best,

I am using gnuradio companion to run a simple test, in which I just connect
a signal source to an audio sink. They have the same sample rate, and the
signal source is a sine wave, amplitude is 0.1, frequency 1kHz, offset 0.
When I make the sample rate for both to be 48kHz, the audio is very chopp
Audio subsystem support out of a VM is kind of hit-and-miss.
Make sure that your emulated sound subsystem is actually running at the rate you request.

Hi,
I seem to be having a problem where GRC works fine but when I execute the
generated Python code (from within GRC or from command line) it just
segfaults. So far it's every flowgraph I've tried. The flowgraph I am
working with is just a sine source, throttle and WX scope.
Where can I start wit

Only thought is a bad or strangely compiled version of Boost.
The last is related to an OSX problem Michael and I ran into yesterday
where Boost was compiled by a much older ve
I know that a source block of live IQ samples set to a certain sampling rate is
equivalent to a File source of IQ samples followed by a Throttle block set to
that same sampling rate. So far so good.
But suppose the system cannot keep up with a live IQ stream, or the equivalent
File + Throttle a
Hi all,
I'd like to know if it's possible to read the GPSDO data (more specifically
the GPS time) with GNURadio-companion. I understand there are simple
commands to read this data in C++ or python, and I'd like to know if it's
possible in GRC.
I'm familiar with programming GRC blocks and
