录制自己的一段语音，时间控制在15秒到30秒左右；利用wavread函数对自己的语音进行采样，记住采样频率。 （1）画出原始语音信号的时域波形，而后以1秒为间隔，求出每秒数据的功率谱。 （2）根据语音信号特点，分别设计FIR及IIR滤波器，分别画出滤波器幅频和相频特性曲线。用设计的滤波器对信号滤波，画出滤波后时域波形。用sound函数回放语音信号。 （3）求出特征频段语音信号随时间变化的曲线（每间隔0.05秒求一次功率谱）。 (Record your own voice for some time (15 seconds to 30 seconds) use wavread function of the voice samples, remember the sampling frequency. (1) Draw the original speech signal in time domain waveform, and then to 1 second intervals, the data obtained power spectrum per second. (2) According to the voice signal characteristics, FIR and IIR filters were designed, namely to draw the amplitude and phase frequency characteristic curve. With the design of the filters on the signal filtering, to draw the filtered time-domain waveform. Playback with sound function of the speech signal. (3) Find the characteristic band speech signal curve over time (0.05 seconds intervals seeking a power spectrum.))

Mixture of Gaussian is an example of matlab code that plot miture of more than one gaussian.

matlab源程序，实现了自适应滤波器中LMS自适应算法。(matlab source code to achieve the adaptive filter in the LMS adaptive algorithm.)

This M-File imports data from binary *.dat files, created with PSpice 6.0 (DOS), 9.1 (Student), and 10.0.3. If you are using newer versions of PSpice, you might need to adjust the code.

可以完成地震记录的合成，实现地震记录的正演模拟(Synthetic seismogram can be done to achieve forward modeling of seismic records)

1st FIR filter is given and wee need to find 2nd FIR filter that meet magnitude complementary criterion. fminsearch is used for error minimization.

说明：  matlab实现模拟退火,程序实现很有效果(matlab implementation of simulated annealing, the program to achieve very effective)

2nd one, this is the next file for code

可以用来求信号的均值，滑动系数可以进行更改，速度很快(Can be used to request the signal mean sliding coefficient can be changed fast)
