单片机PWM的实现原理及方法,了解PWM的工作过程(Single-chip implementation of PWM principles and methods to understand the working process of PWM )

说明：  介绍了一种用加速度传感器测量振动位移信号的方法。 该方法采用频谱转换法，首先将加速度谱转换成位移谱，再计算出位移谱中每个频率分量对应的幅值 、圆频率和初相角，最后对各位移分量进行叠加得到振动位移的时间历程。 验证试验结果表 明该方法 可行 ， 精度可满足工程 实践的需要 。(A method of measuring vibration displacement signal with acceleration sensor is introduced. In this method, the acceleration spectrum is first converted into displacement spectrum, and then the corresponding amplitude, circular frequency and initial phase angle of each frequency component in the displacement spectrum are calculated. Finally, the time history of the vibration displacement is obtained by superimposing each frequency component. The test results show that the method is feasible and the accuracy can meet the needs of Engineering practice.)

这是一本超声波2级考证的一本书，也是超声波专业学习者和研究者的基础书籍，很实用的。(This is a book about the ultrasonic level 2, and it is also the basis of learners of ultrasonic professional and researchers books, very practical.)
