Hello-
I am interested in determining the rms strength of the carrier of an AM
modulated waveform, and displaying it in realtime, perhaps as a windowed
average value. I am using the LFRX boards on the USRP. This question probably
comes up a lot in the SNR and RSSI related posts, but perhaps n

What very interesting timing. (Ugh, pun not intended.)

Hi all,
I want to make a simple hard limiter block (hlimit_ff()) which works as follows:
if input<0
output=-1
else if input>0
output=1
else
output=0
So, in essence, I have downloaded the tar ball
gr-how-to-write-a-block-3.2.tar.gz and replaced 'square' with 'hlimit' in the

I have an application that's running on some fairly "spartan" hardware,
so I'm trying to find ways to make the
flow-graph more computationally efficient, so that I have more
headroom for inevitable feature creep.
Part of my flow-graph has a FIR bandpass filter, which is followed
immediately by a

Hi, Tom:
Thank you for the suggestion, I'll give it a try.
Thanks

Hey all,
I am trying to continually build up the number of projects on CGRAN. It is
growing quickly! For those of you who don't know of it, it is an archive of
3rd party GNU Radio code and projects:
https://www.cgran.org
We broke 100 registered users recently, and we hit the 20 project mark!

So maybe I should be scaling to abs(complex) instead. Will try this.

Hi! I'm new to gnuradio, and I just got my USRP several days ago. I'm trying to
use it with my Mac running Snow Leopard, and I'm having some issues with some
of the USRP utilities and examples. I've built the gnuradio software from the
head revision in the git repository, with the pre-requisite
