I guess it shouldn’t be very difficult to change in order to get the
is from -BW/2 to BW/2 instead of [DC BW/2 + -BW/2 DC].
Should I modify my python flowgraph or my “log POWER FFT” hier block?
I just need to flip the samples and I guess there is a recommended way
do that. Can numpy.fft.fftshift() do the work?
Many thanks for you help,

That’s normal for FFTW-based FFTs (and a lot of others).
The output goes from:
DC to BW/2
-BW/2 to DC
Where BW is your signal bandwidth.
