WebFirst, your supposed 'radix-4 butterfly' is a 4 point DFT, not an FFT. It has 16 complex (ie: N squared) operations. A typical 4 point FFT would have only Nlog(base 2)N (= 8 for N = 4). Second, you have some supposed w[ ].r and w[ ].i 'scale' factors that don't belong. Perhaps you obtained them from a radix-4 butterfly shown in a larger graph. WebMay 22, 2024 · This results in an L-shaped “butterfly" shown in Fig. 8.4.1 which relates a length-N DFT to one length-N/2 DFT and two length-N/4 DFT's with twiddle factors. Repeating this process for the half and quarter length DFT's until scalars result gives the SRFFT algorithm in much the same way the decimation-in-frequency radix-2 Cooley-Tukey …
