Application background
Transform wavelet (WT) is a new method of transformation analysis. It inherits and develops the localization of short time Fu Liye transform, and overcomes the shortcomings of the window size, and can provide an ideal tool for signal time-frequency analysis and processing. Its main feature is that by changing the characteristics of some aspects of the problem, it can analyze the time (space) frequency, and the signal (function) gradually by the expansion of the signal (function), and finally reach the high frequency time subdivision, and can automatically adapt to the requirements of time-frequency signal analysis, which can be used to solve the problem of Fourier transform.matlab
