FFT标准转换
- 对数进行快速傅立叶变换，得出频谱图像，并对进行滤波器，然后频谱分析，前后对比
FFT
- 快速傅氏变换，是离散傅氏变换的快速算法，它是根据离散傅氏变换的奇、偶、虚、实等特性，对离散傅立叶变换的算法进行改进获得。-Fast Fourier transform, discrete Fourier transform is a fast algorithm, which is the discrete Fourier transform of the odd, even, true, real and other characteristics of the discrete Fourie
