自己编写的滤波器程序，包括低通，高通，和带通，matlab(I have written filter program, including a low pass, high pass, band-pass, matlab)

fp=0.2KHz,Rp=1dB, fs=0.3KHz,As=25dB,T=1ms；用脉冲响应不变法设计一Butterworth数字低通滤波器，观察所设计数字滤波器的幅频特性曲线，记录带宽和衰减量，检查是否满足要求。(fp=0.2KHz,Rp=1dB, fs=0.3KHz,As=25dB,T=1ms；The same method to design a digital low-pass Butterworth filter, observe the design of digital filter frequency characteristic curve, recording the amount of bandwidth and attenuation, check with the impulse response meets the requirements.)

通过输入相关参数，实现三阶累积量的求法。从而避免复杂的计算过程。(By input parameters, the third order cumulant method. To avoid complex calculation process. )

LSI就是这样一种维数约减方法。它可以通过对“文档向量矩阵”进行解奇异值分解（SVD: Singular Value Decomposition）运算，自动计算得到一个比原始空间小得多的有效语义空间(LSI is such a dimensionality reduction method. It can be through the "document vector matrix" for the singular value decomposition (SVD: Singular Value Decomposition) operation, automatically calculated an effective semantic space is much smaller than the original space)
