it is a wavelet based code that will create the second order wavelet transform and subplot it in same image as shown in many matlab examples for wavelet transforms..

基于matlab，针对调幅AM、调频FM和调相PM信号，分析在不同的噪声环境，包括高斯白噪声、色噪声、非高斯噪声及正弦干扰中，各种信号的二阶循环谱。可根据需要改变程序中信号或噪声环境，分析结果。(Based on matlab, AM for AM, FM FM and PM phase modulation signals, analysis of noise in different environments, including Gaussian white noise, colored noise, non-Gaussian noise and sinusoidal interference, the various second-order cyclic spectrum signals. May need to change the process in accordance with the signal or noise environment, the results of the analysis.)

具有微分先行的PID控制方法，可以设置M参数查看控制效果（M=1为微分先行的控制效果）。(PID control with derivative first method, you can see the control effect parameters set M (M = 1 for the first derivative of the control effect).)
