用matlab仿真轴承故障信号构造轴承故障的仿真信号，其中轴承的固有频率fn=3000Hz , 位移常数y0=5, 阻尼系数ξ＝0.1, 冲击故障发生的周期为0.01s，采样频率fs=20KHz, 采样点数N=4096。要求：根据上述条件构造轴承故障的仿真信号，画出其时域波形及频谱图。(Matlab simulation bearing fault signal)

利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)
