I am a newbie in this community so I may pose a very simple question…
I am trying to split via GUI the output vector of the FFT block in two
halves, one with the upper part and one with the lower part -i.e. I
don’t want a duplicate of the output vector-. Say I have a FFT of 1024
points, how do I split the output into the first 512 points and the
final 512 points? This leads me to the related question of how is the
FFT implemented: is the DC component coming first and then the positive
part of the spectrum with fftSize/2 samples to be finally followed by
fftSize/2-1 of the negative part? Or is it some other way? Moreover, is
it normalized by the number of points?
Thank you very much.
