[Discuss-gnuradio] Basic sampling frequency question
I have a really simple question that I can't seem to find the answer to online (and pardon my limited signal processing background). I'm trying to help a fellow colleague figure out a processing problem. An external code modulates a real-valued signal that is eventually fed into GRC. For now the signal is generated with some arbitrary positive center frequency and then a GRC script converts it to complex and then downshifts and centers it at 0Hz. This isn't efficient because the modulation in the external code takes a lot longer with higher sampling frequency. If the external code was modified to put the real-valued signal in the -5 to 5kHz band (centered at 0Hz and assuming a real-valued signal can represent negative frequencies), is the minimum sampling frequency to avoid aliasing 20kHz or is it 10kHz? This is before the GRC script converts it to complex. Thank you in advance.. Tom ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Tom ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio A few things: * A real valued signal has a frequency spectrum that is symmetric around 0Hz. So the negative frequency components are identical to the positive frequency components. * For your case, the minimum sampling frequency would be 10KHz. The signal being real or complex does not make a difference. If a signal occupies frequency -F to F at the baseband (centered), your Nyquist sampling rate is 2F.

Hi Sumit, There are two links that we can use to access the current version of the GNU Radio source: git://gnuradio.org/gnuradio and http://gnuradio.org/git/gnuradio.git . As of now, the second link does not work for me, but the first one does.

get the file from sender and store it in a txt file which is passed as
an arguement. I also added few lines of code so that the receiver
calculates the number of error bits in each packet it receives.

Hope that helps, Chris And it's funny because I used the http: version in the build-gnuradio script specifically because some peoples local firewall rules preclude the use of the GIT protocol. Sigh. Perhaps I'll update the script to try both methods. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio - Sumit Kr.

Re: [Discuss-gnuradio] Accessing commedi drivers through gnuradio

Is there any documentation available for same. Thanks, Abhishek. I don't think that we have any in the code, and I'm not sure if anyone has done it elsewhere. Also, the gr-comedi code has not been touched in a while, so there's no telling what state it's in. If you get it working, please let us know if you had any major problems with it so that we can fix it up again.
