Abstract

Regarding as the fundamental operations of time domain and frequency domain transformation,FFT(Fast Fourier Transformation) is the necessary precondition for the spectrum analysis,and it is widely used in real-time processing of signal.By using TMS320VC5402 DSP as the hardware platform of TI Corporation,this paper analyzes the basic principle of FFT,realizes the real-time fast FFT algorithm and demonstrates the accuracy and feasibility of implementing fast FFT on DSP.It is very helpful for spectrum analysis study.
