Hi,
This is an evolution of a concept that was mentioned at GRcon which I
really liked and I thought a bit more about it.
The general idea is that each block and each port within blocks would
have a "domain" associated to it.
For the blocks this would essentially represent where that block is

Hi everyone ,
I'm doing a small experiment i.e FM transmitter using
gnuradio and usrp b100.i'm facing problem to set the output sampling
rate.How exactly should be the sampling rate at each stage to transmit the
audio file.Below is the grc file of my flowgraph
Please can anyone help
very simple. this is part of my code for reading complex signal, but mind
that i have separated real and imaginary values, there is a way to read in
an array of complex i suppose.
file = fopen(read_path, 'r');
%fseek(file, 194*8, 'bof');
data = fread(file, 'single', 'l')
Hi JPL,
.mat is really just a complicated container format for all kind of matlab data
-- GNU Radio can't directly deal with that, although with SciPy you could
create something that will be able to parse .mat files; but that is quite
useless, as you could as well use Matlab to write something
Hi list,
I am designing very simple FSK modulator. The principle of operation is
following:
based on symbol value nco generates baseband signa. The problem is
somewhere in my forecast function, but I can't figure out where, probably
because of misunderstanfing of something.

Hello all
just looking for some help regarding the USRP N210 in GRC.
I'm having a problem with the IP address in GRC.
I have looked around but the only material I have found regarding IP address
relates to setting up the N210 on the network.
That part I have correct.

Thank you Martin, I will try with the sync_decimator, but it is also
important for me to unterstand what's happening here.
So, I have vector source -> throttle -> fsk_modulator -> scope sink.
Vector source generates 8 symbols. From where scheduler starts, from source
or from the sink? And why it di

You need to specify addr="IP", not just the
Thanks for the reply Martin
yeah I got it now. I had actually tried that but I put:
addr="192.168.10.2"
in the address field where it should be:
addr=192.168.10.2
Thanks again

Thanks Nemanja.
Have you ever try reading Byte data in Matlab?

I think it might be good for whoever would be interested in VOLK to
get together for another meeting in a couple of weeks to discuss any
progress and to include anyone who was not at the inaugural meeting at
GRCon.
A rough agenda:
* Data collected so far from pybombs -- what can we get out of it
*
Parameters you pass to UHD like this are not persistent between runs, the
hardware is re-initialized each time so you must pass them each time.
In GRC you would pass the parameters as per the example I've attached.

Hello,
I'm trying to make an FFT block in my hierarchical block, but I cannot seem to
find the correct syntax.
I'm trying to make it with a BLACKMAN_HARRIS windowing function, and it's easy
in a python program:
fft_forward = fft.fft_vfc(window_size, True,

Hello,
I found out two *.grc files, tx_ofdm and rx_ofdm, under
gr_digital/examples/ofdm.
Don't know if this can be realized,
first test running the steps without changing any parameters in *.grc.
(A) use *.dat generated from Matlab (I saved a set of wav audio),
(B) place it as input in the tx_ofd
