Re: [Discuss-gnuradio] scalar and vector streams

[Vincenzo Pellegrini]

thanks Josh,
it worked fine!

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 <address@hidden>:

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
