Hello again,
Can a radix-4 fft be used to construct any type of radix-2 fft. e.g. can I manipulate a 64 pt radix-4 fft to give me a 128 pt radix-2 fft ? If so, is the radix-2 fft of any use in dsp as it usually results in larger and slower ffts than the radix-4 version.
As always thanks for all replies.
