Hey guys,
I just had a quick question; if we have multiple streams that need to be
decimated, is there a fast way to go about doing that in GNURadio
Companion? How would you do it?
Here's a picture of my flow graph: http://imgur.com/a/a0KCX
Thank you for your help!
Best,
Ali

Martin, I will revisit them. At this early stage, at each iteration I
absorb some more. Your note implies my answer is there, so off I go...

Hi Activecat,
I still don't understand; do you really just want a offline data
periodogram?
In that case, have a look at the python matplotlib library examples.
Also, Martin's and Lou's statements still stand: just by labeling an
axis dBm doesn't make the data actually represent that physical
Equivalent function here, which could be encapsulated into a GR block if you
don't need speed:

I suppose it boils down to the difference between an FFT just normalized to
bandwidth, and the FFT of the
I added
set(GR_REQUIRED_COMPONENTS RUNTIME FILTER)
set(GR_REQUIRED_COMPONENTS RUNTIME FILTER DIGITAL)
and
${GNURADIO_ALL_LIBRARIES}
to my CMakeLists.txt and the problem solved,
but It's interesting that I had to edit CMakeLists.txt to make it work, I
thought gnuradio would do it

Hello Marcus ,
thank you
I found
find_package(Gnuradio 3.7.2 REQUIRED)
in my CMakelists.txt file
and the output for gnuradio-config-info --version is
v3.7.6.1-103-g8ecfd13a
is this the problem? How do i fix that?

Dear Sirs,
Thanks for the answers. Let me further elaborate.
I could get what I want using Matlab, via below steps:
1). Using GRC flowgraph, connect the USRP Source to a File Sink.
2). Copy the file (says, test02.dat) to a PC running Matlab.
3). Using Matlab, run these commands:
a). c
The gr-specest toolbox has all sorts of spectrum estimation algorithms,
but they also don't calibrate your device. A periodogram would be in
there, called 'welch'.

A few weeks ago I started learning my way around gnuradio and am making
progress, but could use advice from experienced users.
I've been making something of an online lab notebook recording my
efforts in gnuradio at:
