Hi Eric, Thanks for getting back to me. I'll look into the fftw docs and the links you gave to understand the details.

I suggest that you take a look at the docs on www.fftw.org. Our fft block uses FFTW to do the work, and the output is exactly as they specify. http://www.fftw.org/fftw3_doc/The-1d-Discrete-Fourier-Transform-_0028DFT_0029.html#The-1d-Discrete-Fourier-Transform-_0028DFT_0029 For a good intro to DSP, see "Understanding Digital Signal Processing" by Richard Lyons.
