本文讲述锁相环的工作原理，锁相环路实际上是一个相差自动调节系统。(This article describes the working principle of PLL, PLL is actually a difference between the automatic adjustment system.)

matlab的简单小波处理程序，可以进行5层分解，更多层次分解，可以稍作修改 就行。(Simple matlab wavelet processing program, you can break down into five layers, more hierarchical decomposition can be slightly modified on the line.)

程序给出了0~10发音的语谱图，其中采用分帧函数对信号进行分帧处理然后在用fft算法得到频谱信息，后用灰度图像表示(Program gives the pronunciation of words from 0 to 10 spectra, which employs the signal sub-frame function and then in the sub-frame processing spectral information obtained with the fft algorithm, then said with a gray image)
