Re: [Discuss-gnuradio] Announcing USRP/GNU Radio and RFNoC Workshops in the Los Angeles Area

Hello Neel, Sounds great! Do you have such workshop plans in Europe, probably in France/Germany. Recently I attended the NI workshop on the same during ICC 2017 Paris, but due to some reasons the agenda was not covered during the workshop. And it was very short also. I am very much interested

Re: [Discuss-gnuradio] Rounding errors in PFB channelizer?

Hi Marcus -- First, thanks for catching the typo in the channel map. There was no plan to skip any channels; the goal is to get each channel in frequency order (out0 = 540 kHz; out116 = 1700 kHz). I did an experiment using a signal generator feeding the Red Pitaya receiver and testing

Everything is now clear! Thank you for the patience and sorry for my little knowledge. Thanks to rear1019, Marcus and MLD Alice Il 29/11/17 20:32, Michael Dickens ha scritto: Hi Alice - Inside "work" or "general_work", all you have is access to is pointers to buffers. The "shape" of them is

Re: [Discuss-gnuradio] Output block: vector of a vector

Hi Alice - Inside "work" or "general_work", all you have is access to is pointers to buffers. The "shape" of them is inferred by the block implementation specifics, for example a pointer to unsigned char array, or pointer to float array. Recasting pointers as you describe will cause a crash,

[Discuss-gnuradio] problem with Tagged File Sink

I have a custom block that is adding the "burst" "True" and "False" tags via: add_item_tag(0, d_total_passed_samples, pmt::mp("burst"), pmt::mp("True")); and add_item_tag(0, d_total_passed_samples-1, pmt::mp("burst"), pmt::mp("False")); When I run it and look at the output via Tag Debug, I

Does the number of channels have to be a power of 2? On Wed, Nov 29, 2017 at 10:39 AM John Ackermann N8UR wrote: > I'm building a ridiculous flowgraph that breaks the AM broadcast band > (540 - 1700 kHz in the U.S.) into 117 10 kHz wide channels and measures > the energy in each.

[Discuss-gnuradio] Output block: vector of a vector

Hi, I'm wondering if it is possible to make an output of a block that is a vector of a vector. I tried with:     int     vector_source_tagged_impl::work(int noutput_items,     gr_vector_const_void_star _items,     gr_vector_void_star _items)     {   std::vector *optr =
