数字信号处理matlab实验用FFT做谱分析源代码，可放心使用(Experiment with digital signal processing matlab FFT spectrum analysis to do source code can be freely used)

说明：  模型降阶方法 MATLAB schur方法(Using matlab to program the control system )

matlab中同步电机在dq轴系下的建模，转子绕组短路定子绕组突然加对称电压，有阻尼绕组，自己用S函数编的，很好用的哦，适用于初学(matlab modeling of the synchronous motor in dq shaft under the rotor winding short-circuit the stator winding suddenly and symmetrical voltage damper winding, S function series, very good used, suitable for beginners)

已知地震加速度记录，可以用来求速度的时间历程。(Known seismic acceleration records can be used to time history and speed.)

本算法是通过共振峰的方法，利用信号的倒谱特性对语音信号进行处理。(This algorithm is the method by the resonance peak, the signal characteristics of the cepstrum of the speech signal processing.)
