对数组各个变量进行方差分析与模糊聚类，次程序可将其分为三类(An array of each variable variance analysis and fuzzy clustering, time can be divided into three kinds of the program )

FIR滤波器，使用hamming窗函数，对正弦信号的傅里叶分解形式进行滤波(FIR filters, using hamming window function, Fourier decomposition form sinusoidal signal filtering)

it will calculates the SNR if u give noise,clean,noisy speech files as the input it will gives the SNR.
