FFT

Hi

I have been trying to calculate FFT based on Radix-4 in Excel. Also I have been comparing my result with matlab. But I am stuck at the moment because I felt something did not seem to be correct. Please find the attached file.

Any help would be appreicate

Hi, in the Radix-2 algorithm Decimation in time for 2 iteration for 8-point DFT, why do we keep the twiddle factor to W(0,8.0) and W(2,8.0) where normally we go in the series W(0,8), W(1,8)...

If I'm not clear, please read my question and look at the implementation of 8-point DFT using 2-point DFT by FFT DIT method

the smiley represents eight, for some reason numerically writing eight and bracket coverts it into a smiley
