在matlab下实现信号频谱分析：利用快速付里叶变换FFT得到下列信号的频谱，并绘制信号及频图形：1.长2s的方波信号，频率f=10Hz -In matlab signal spectrum analysis: the fast in leaf transform FFT get pay of spectrum, the signal and drew the signal and frequency graphics: 1. The long 2s, frequency f = squar

当前信号处理中，对频谱的研究不断深入，本书中讲述如何使用快速傅里叶变化进行频谱变换，和图像相关性分析，信号处理- How to use FFT2 The note explains in detail how to apply the Matlab 2-dimensional FFT for filtering of two-dimensional signals, e.g. images. It is shown how to connect the output from fft2 to t

分析宽带信号频谱，应用fft变换，使用matlab进行分析-analyze the frequency spectrum of signals in matlab
