信号FFT谱分析算法及实现探析

Signal FFT Spectrum Analysis Algorithm and Implementation Study

快速傅里叶变换技术已成为数字信号处理强有力的工具。本论文尝试分析利用该算法实现图像去噪，还给出一种用Madab系统实现信号频谱分析与显示的方法。

Fast Fourier transform techniques have become powerful tools for digital signal processing.This paper attempts to analyze the use of the algorithm for image denoising,hut also gives a signal with Matlah system implementation and display spectral analysis method.
