Hello, I guess it shouldn't be very difficult to change in order to get the output 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 to do that. Can numpy.fft.fftshift() do the work? Many thanks for you help, Jorge. On Mon, 19 Jan 2015 08:46:22 -0500, Marcus D.
