[Discuss-gnuradio] Newbie question that I can't seem to find an answer to

[Bennett, David S. (Scott)]

Does a stream-to-vector block buffer the input stream?  For example, if I want to create a length 2048-sample vector from a stream, is the vector updated every 2048 samples?  Or is it updated every sample?

 

I want to feed an FFT block with a 2048-sample vector and I want to make sure that I’m not doing a new FFT every sample.

 

Thanks,
Scott Bennett
