Re: Time Partitioned FFT

2022-08-05 Thread Chris Kuethe
Why? How would this work on a 2-core ARM SBC vs some fancy 32-core workstation? What about the incoming sample rate? Are you getting 2Msps from an RTLSDR, or 200Msps from a very powerful instrument? And how many points is your FFT? What are you doing with the output of the FFT? 1000ms / 40ms inter

Time Partitioned FFT

2022-08-05 Thread Elmore's
Is it possible to use GNU radio to perform time partitioning of FFTs? I would like to be able to start an FFT and run it for 160 ms. A second one would start 40 ms after the start of the first and run for 160 ms. A third would start 40 ms after the start of the second. This process would continu

Is there any way to tell scheduler, that our block needs certain amount of items on input?

Dear Gnuradio community, Is there ability to tell scheduler to call work functions only when ninput_items will have value I set manually in constructor? thanks in advance! Niko

My block doesnt propagate tags, despite propagation policy set

2022-08-05 Thread Nikoloz Glonti
Dear Gnuradio community, I have a problem - my block doesn't propagate tags from input 0 to output 0 despite i set tag propagation policy in constructor to TPP_ONE_TO_ONE. Also, It can't detect tags in incoming samples when i call get_tags_in_window(d_work_tags, 0,0,noutput_items); for (co
