利用matlab对齿轮箱3种状态进行HMM模型建立及测试，已调试好，可直接运行。(Use matlab gearbox three kinds state HMM modeling and testing, debugging, and can be run directly.)

根据FSK调制原理 在二进制频移键控中，幅度恒定不变的载波信号的频率随着输入码流的变化而切换（称为高音和低音，代表二进制的1和0）。来做实验 (According to the principle of FSK modulation in the binary frequency shift keying, the frequency of the carrier signal amplitude constant with the change of the input stream is switched (called treble and bass, representing a binary 1 and 0).
