对采集信号进行仿真，通过旋钮可以调节信号的幅度，还可以改变波形-The collected signal simulation, the signal can be adjusted by the rate knob, you can also change the waveform

二相编码信号，频率编码信号的时域和频率仿真波形-A two-phase coded signal, a frequency-coded signal, and a frequency-controlled waveform

利用MATLAB程序仿真轴承内圈不同故障程度信号。仿真信号X由故障信号 与白噪声r两部分构成(Use MATLAB program to simulate the signal of different failure degree of bearing inner ring. Simulation signal X consists of two parts: fault signal and white noise r)
