Re: [Discuss-gnuradio] How can I separate and count the IQ samples stored

Hello Julio, it's not really clear what you're asking. Could you explain what you're looking at, what your system is, and what the problem you're encountering is? Best regards, Marcus On 08.09.2015 06:41, Julio Hector Aguilar Renteria wrote: > How can I separate and count the IQ samples stored

Hey Michael, Hey Kevin, Hey all, thanks for your help! I found that by specifying the python version I want to use when running the file, everything works fine. Like this: python2.7 if_else_mod.py This would be acceptable for me, however, I decided to do some of the stuff you suggested. I

Re: [Discuss-gnuradio] How can I separate and count the IQ samples stored

File source (no repeat) -> complex to float -> 2 file sinks; one writing to "real.f32" and the other going to "imag.f32". Take the size of each output file and divide by 4. That's how many samples are in each. On Sep 7, 2015 9:41 PM, "Julio Hector Aguilar Renteria" wrote: >

You need to do it from the same, unmodified directory where you did "make install" last. If you deleted that, the information which files have to be uninstalled are lost. You can only hope for the best and install over without deinstallation first. Best regards, Marcus On 08.09.2015 23:02, Rama

Re: [Discuss-gnuradio] ssb - question

Unless you're building the IQ modulator with real signals for educational purposes, go with the flowgraph Ron mentioned. Multiplication by a complex sine is much easier. You can also use a Rotator or Frequency Xlating Filter to do similar things. The bandpass filter can be built in to the

Your first problem is that you're using a 32k sample rate with a 20k sin/cos. This will actually come out as a 12k sin/cos, due to aliasing. Try the same thing again with a 48k sample rate and see what happens. Either bandpass filtering or a Hilbert transform can be used to create SSB. Not
