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.
