Algorithm Real FFT/IFFT

Started by Dmitry December 8, 1999
Hi All.

I use ADSP-21xx for audio applications. I must to transform ADC data
to the power spectrum, to modify the spectrum and to trasform it back.
Therefore, I need in the detailed FFT and IFFT of real data. How to
pass from real data to complex correct? Standard fft() and ifft() from
the ADI has small uncorrect details. If you used FFT and IFFT success,
please send me only algorithm.

Best Regards, Dmitry.
