thanks Josh, it worked fine! vincenzo
PS to obtain an ifft instead of a fft,i should use gr.fft_vcc with the boolean argument "forward" set to false, right? PS2 is there any other paper available describing the gnuradio blocks, apart from DaweiShen's tutorial 9? 2007/2/18, Josh Blum <[EMAIL PROTECTED]>:
you should use gr.stream_to_vector(nbytes, fft_size)-->fft-->gr.vector_to_stream(nbytes, fft_size) nbytes will be 8 for complex data input/output -Josh Vincenzo Pellegrini wrote: > hello, > first of all thanks to everybody in the list for the huge amount of > suggestions about hard-disk reading speeds I was provided with a few > days ago. :) > > then another question: which is the wisest way to convert a scalar > stream to a vector stream and then back to a scalar stream within a > python flow graph.. if there is one, of course! > > what I'm trying to do is: > > source_c--->gr.fft_vcc--->rest_of_the_flow_graph_c > > is this reasonable? > > > best regards > vincenzo > > > > _______________________________________________ > Discuss-gnuradio mailing list > Discuss-gnuradio@gnu.org > http://lists.gnu.org/mailman/listinfo/discuss-gnuradio > >
