采用的是脉冲对消法，在matlab R2009b调试通过，主要是基于mtlab的程序，仿真图是速度、距离、幅度三维图像，数据模型归一化，模态振动，使用起来非常方便，分析了该信号的时域、频域、倒谱，循环谱等。- It uses a pulse of consumer law, In matlab R2009b debugging through, Mainly based on the mtlab procedures, FIG simulation speed, distance, amplitude three-dimensional image, Normalized data model, modal vibration, Very convenient to use, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc.
