TI 54x fft
- DSP编程代码,FFT算法,经典!! FFT实验 一、 理论: 公式(1)FFT运算公式 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。如此一来,计算时乘法次数和加法次数都是和

spwm6
- 这是个SPWM的六路输出程序,采用的是规则对称算法,虽然改变了占空比,但波形不对。现对程序的几点说明如何,其中K的初值,我设置的是1,因为我采用的是下益中断,这样的话程序在发生第一次中断之前已经进行了两次跳变(两次和比较寄存器匹配)。这个程序输出的波形通过低通滤波器之后出来的不是个正玄波,希望高手们能给分析一下,以下是我的邮箱liuhao511zz@sina.com.cn-spwm
