fft algorithm - twidle multiplication
$begingroup$
im trying to understand how fft(fast fourier transform) algorithm work and after watching several videos i couldn't understand why there is multiplication with Wn in this specific places and why the power of w is what it is..? is there any rule that i should working according to it?
im adding a picture of the fft diagram and the w in blue circle.
thnx in advanced
the pic is here
