说明：  其中人为一个抽象类，其属性包括姓名、性别、出生日期等(One human an abstract class, whose properties include the name, gender, date of birth)

最小频移键控（Minimum Shift Keying，MSK）是一种具有连续相位和最小频偏的数字调制技术。MSK的突出优点是信号具有恒定的包络和信号的相位连续性，频带利用率高，信号的功率谱在主瓣外衰减较快，这就使得它对邻波道干扰小。(MSK (Minimum Shift Keying) is a continuous phase and the minimum deviation of the digital modulation techniques. Outstanding advantage of MSK signals have constant envelope and continuous phase signals, high bandwidth efficiency and the signal power spectrum decreases rapidly outside the main lobe, this makes it a small adjacent channel interference.)

simulink仿真学习的必备教程，里面有许多例题，学完你就是高手！(simulink simulation study of the essential curriculum, there are many examples of school after you are a master!)

说明：  在matlab中，以simulink为主要工具介绍了系统仿真方法与技巧，包括连续系统、离散系统、随机输入系统和负数系统的仿真。(In matlab in order to simulink introduced as the main tool for system simulation methods and techniques, including continuous systems, discrete systems, stochastic systems and the negative input of the simulation system.)

此压缩包包含两个程序，一个为录音程序，另一个为放音程序，皆用MATLAB编写，可以改变采集信号的频率和指定播放频率。是在学习数字信号处理中用到的一个小练习。欢迎尝试运行，和进一步修改。(This compressed package contains two programs, one for recording the program, and the other for playback program, are using MATLAB, you can change the frequency of collection and the specified playback signal frequency. Digital signal processing is used to learn a little practice. Welcome to try to run, and further modified.)
