FFT v9.0

941 Views

Hi, I'm using FFT megacore v9.0 in streaming architecture to calculate 1024 point fft. My input to the FFT is from the NCO megacore. All the control signals (sop,eop etc.) are proper. Yet I'm getting the source_exp value as +35. Is that possible?

And my FFT output is not periodic even though my input is periodic.

Also I've not windowed my data before passing it on to the FFT block. Is windowing necessary?

Please help!!:cry::cry:
