说明：  我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. (We know that a wavelet transform decomposition process is that the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and Multi-level decomposition is a decomposition of the previous low-frequency coefficients to be further wavelet decomposition is a recursive process. Following is a one-dimensional wavelet decomposition process.)

因为傅立叶变换对应的是无限信号,信号经过分帧后变成有限信号,分帧的信号再进行傅立叶变换后,高频部分将有 泄露 ,所以要加窗. 窗函数的拼谱都是在某高频部分截止,所以每帧信号加窗后的傅立叶变化,频谱基本 泄露 (Because Fourier transform corresponding is infinite signals, signals after framing become limited, framing signal again after Fourier transform, the high frequency part will have leaked , so to add window. Window function spell spectrum are in a high frequency part of the globe, so each frame and window after Fourier transform, signal spectrum basic leak )
