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N^2 成正比的,当N 很大时,运算量是可观的,因而需要
改进对DFT 的算法减少运算速度

傅里叶变换能将满足一定条件的某个函数表示成三角函数(正弦和/或余弦函数)或者它们的积分的线性组合。在不同的研究领域,傅里叶变换具有多种不同的变体形式,如连续傅里叶变换和离散傅里叶变换。最初傅里叶分析是作为热过程的解析分析的工具被提出的-Fourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions
