Cross_spectra The Cross Spectum.In normal spectral analysis the spectrum shows how energy is distributed in frequency (or wavenumber) space. This can be obtained either by taking the fourier transform of the lagged autocorrelation. The lagged autocorrelation is infact the convolution of a time ...
The Matlab code presented here is an example of Cross-Synthesis – a technique of impressing the spectral envelope of one sound (modulating signal) on the flattened spectrum of another (carrier signal), consisting of the following steps: 1. Short-Time Fourier Transform (STFT) of both the ...
通过在MATLAB小波工具箱中选择合适的Coif5小波基函数对波形信号进行一维连续小波变换,发现从变换后得到的小波系数线及其最大值可以得到反映桩身应力波传播的更多有用信息,消除了由实测信号直接读取反射波特性所存在的误差,从而准确地判断出了桩长和缺陷的位置。
