[Discuss-gnuradio] Stream selector and changing variable after N samples

2013-12-05 Thread Aylons Hazzud
I have been experimenting with the stream selector in gnuradio companion, but am stuck in situation. First, how do I change a variable after N samples? I want the signal to switch from a filter to another at a fixed rate, but blks2.selector uses a variable to do the switching. So, how could I

[Discuss-gnuradio] Switching between simulated channels

2013-12-04 Thread Aylons Hazzud
I have been using GNURadio lately as a simulation library, kind of expading SciPy for static analysis while making some real-time analysis for parameter tweaks now and then. It's working great. However, I have a problem I would like to solve better: I have a switching data input, where the same

2013/10/23 M Dammer i...@mdammer.net: I have no answer here. But talking about Gnuradio and nuclear physics I want to add my idea to your question: Would it be possible to use Gnuradio in a (home made) Gamma Spectrometer ? These spectrometers usually work with a multichannel analyzer that

2013-10-23 Thread Aylons Hazzud
Hi, people. Anyone here has experience using Gnuradio or USRP as an instrumentation tool (I mean, not for actual radio transmissions)? After years studying, hobbying and working with SDR, I've just learned that they are very similar to particle acceleator instrumentation, in a very pleasant way:

I don't have high hopes for this specific chip - I guess the IC will be hard to buy and the modem feature on built devices will hard to hack, lacking source and documentation for its drivers, just as Android devices are hard for cyanogenmod developers to hack with. But these news do give some
