可以实现有效数字、杨氏模量及牛顿环等计算(Can achieve significant figure, Young s modulus and the Newton s rings and other computing )

横坐标是时间，纵坐标是频率，matlab绘制时频图的小程序(Time frequency pic)

说明：  本代码提供了一个无线传感网路由协议的仿真，适合于初级学者。(This code provides a wireless sensor network simulation by the protocol, suitable for junior scholars.)

用于求多多数据的均值和方差，希望对大家有用(Seek more data for the mean and variance, in the hope that useful)

本程序可以对一个模拟信号进行数字化，使用的是PCM即脉冲编码调制，其结果是将样值转化为8位PCM编码。现今语音编码大多数采用这类编码方法(This procedure can be an analog signal to digital, using pulse code modulation or PCM, and the result is kind of value will be translated into eight PCM coding. Most of the current speech coding to adopt this type of coding method)
