hi ben,
i'm not sure which FFT you are using.
if you are using the biplex FFT, this computes
two complex FFT's at once:
two complex data streams go in,
each with 2^N complex points,
and two 2^N complex point streams come out. (not 2^(N-1)).
i think the frequency ordering of the biplex FFT is most
negative first (the first complex point after the sync pulse), followed
by less negative, then 0, then slightly positive and to highest positive.
the wideband real and wideband complex fft's have multiple streams
coming in and out in parallel to handle higher data rates than the FFT
clock.
best wishes,
dan

I think I didn't state question 2 correctly.
2) The output of the 2^N point complex FFT is 2^N-1 complex channels.
What is the frequency ordering of these channels?
Thanks,
Ben
