Found this mail, it seems that the DC removal is still on implementing? If
so, the tune request can not solve the DC problem at all?
Sorry for these questions, as I am really confused by the code and the
observed phenomenon.

Hi Comunity,
I have just uploaded some more screen casts. There are 6 of them.
One is about basic hacking with the dial_tone.py script so that the
beginners get a flavour of doing customization without knowing much of the
language paradigms.

Hi,
is there any literature that goes with the FLL synch blocks in
gr-digital? Ironically, Google always points me to the GR source files
when I search for 'fll band edge' related topics.

Hello,
Frederic Harris's "Multirate Signal Processing: for communication systems"
has a section on FLL band edge sync. I think that the GR-digital code was
designed based on these algorithms. Tom or other GNUradio block designers
can verify it.
Thanks,

I tried to find in the QT GUI Widgets category an item that does FFT. But
don't find one. I wonder what is meant by the "QT GUI FFT display"?
Thanks,

As sanity check I'm trying a simple flowgraph in GRC with a QAM mod/demod:
Vector Source ==> Throttle ==> QAM Mod ==> QAM Demod ==> Unpacked to Packed
==> File Sink
The parameters in the mod/demod are as default. I also have a File Sink
before the mod.
In the output I see first a bunch of zeros,
Well I should have been more patient before I sent out the last email. It
turns out for the functionality I want (flexible zoom in display of the fft
spectrum) the block is called simply "QT GUI sink", if I am not mistaken.
When I tried, there is the error message:

Thank you very much for your help Josh! I'll let you know if we end up
going this way in our design.

Yes, you should be able to set up an io_signature just
What does the TCP sink do in server mode before any connects? Does it
drop samples, or stall the pipeline?

I think thats a little python wrapper around a gr file descriptor sink
and a python tcp socket. The block's constructor blocks waiting fo

Dear Group,
I need to clarify a very basic feature of the USRP ADC. The question is:
Does the ADC have internal noise dither when sampling? I looked at the TI
ADS62P45 data sheet but did not find explicit mention of the noise dither.
On the other hand, if you read those app notes from Analog Devic
