| Abstract: | It introduced the theory of split radix FFT algorithm in this paper.DIT(decimation in time) and DIF(decimation in frequency) split radix FFT subroutines were programmed,and computing efficiency between split radix FFT and Cooley-Tukey algorithm were compared.Finally,some viewpoints on split radix FFT teaching were put forward based on the teaching practice of digital signal processing course. |
