| Abstract: | The FFT algorithm principle is analyzed, make use of DSP Builder to have built 8 points of the decimate in time（DIT） radix -2 fast Fourier transform（ FFT）, has separately carried on the simulation in Simulink and Quartus Ⅱ. Then the author imitated the simulation result and the true value of Matlab to carry on the comparison, realized 8 points of real number sequence FFT algorithm, had the design based on the DSP Builder FFT algorithm to be simple, may duplicate uses, greatly enhanced the rated capacity. |
