MATLAB-Wavelet-transform
Matlab小波变换与傅立叶变换用于检测阶跃信号，原始时域信号是一个阶跃信号，为了确定阶跃信号的突变点，分别采用傅立叶变换和db5小波进行处理。(Matlab wavelet transformation and Fourier transform is used to test signal, the original order jump time signal is a step road signal, in order to determine the Laplace domain signals point mutations, respectively the Fourier transform and db5 wavelet for processing.
