I have just started working on FFT and its related phase factors.
I have read for an N=2 point FFT, We have two phase factors, one on the positive axis and one on negative axis.
similarly for an 4 point FFT, we have 4 phase factors as theta=(pi/2), at
0' W 40=1 -90' W 41=-j 180' W 42=-1 90' W 43= j
here we can see the values that are 180 degree apart are negative to each other.
Here I wanted to know how it works for an 32 point FFT.
As theta=(pi/16) do we have 16 phase factors on the positive axis and 16 phase factors on the negative axis with the interval of (pi/16) ?
so will it follow the pattern as I mentioned below?
0' W16 0 =1 -11.25' W16 1 =0.98 -j0.195 -22.5' W16 2 =0.92 -j-0.38 and so on .... .... till -168.75' W16 15= and the negative parts of the above values from **W16 16** to **W16 32**
Am I correct? please verify the above details and let me know how the phase factors works for an 32 point FFT
Thanks in advance
