[DSP program] Lab0503-FFT DL : 0: 用dsp实现快速傅立叶变换(FFT)算法，FFT 并不是一种新的变换，它是离散傅立叶变换（DFT）的一种快速算法。由于我们在计算DFT 时一次复数乘法需用四次实数乘法和二次实数加法；一次复数加法则需二次实数加法。每运算一个X（k）需要4N 次复数乘法及2N+2（N-1）=2（2N-1）次实数加法。所以整个DFT运算总共需要4N^2 次实数乘法和N*2(2N-1)=2N(2N-1)次实数加法- Dsp to achieve the fast Fourier transform (FFT) algorithm, the FFT is not a new transform, which is a fast algorithm for the discrete Fourier transform (DFT).Since the time when we in the calculation of DFT complex multiplication required four real multiplications and secondary real additions a complex additions need to quadratic real additions. Each operator a (k) 4N complex multiplications and 2N+2 (N-1) = 2 (2N-1) times the real number addition. Entire DFT operation a total of 4N ^ 2 real multiplications and N* 2 (2N-1) = 2N (2N-1) real additions
