语音增强算法，性噪比，原信号与增强后信号对比(Speech enhancement algorithm, sex ratio, the original signals and enhanced contrast )

Design a linear phase minimum order FIR Band Stop filter to stop the frequency band 0.45π to 0.55π with atleast 60dB attenuation at the edges. Further -3dB frequencies are required to be at 0.3π and 0.7π. 1. Plot the frequency response of the psuedo magnitude function using (a)rectangular window, (b)Hann window and (c) Hamming window. 2. Plot the frequency response for Rectangular and Hamming window for a length of 1024 to demonstrate the fact that the increase in the length, doesn t reduce undershoot and overshoot in Rectangular window.

说明：  1.相关分析法辨识系统程序。2.方波响应与阶跃响应的互相转化的通用程序。3.获取系统模型阶次的函数。4.levy方法辨识系统的函数。5.将相关分析法的辨识结果转成频率响应的程序((1) analysis Identification System program. 2 square wave response and step response of the general program of mutual transformation. (3) for the function of the system model order. 4.levy method recognize the function of the system. The identification of the relevant analysis results converted to the frequency response of the program)

基于Matlab语言的Monte_Carlo入门教程，非常实用！(Based on Matlab Monte_Carlo introductory tutorial, very useful!)

matlab粗糙集算法，主要使用于神经网络和支持向量机等算法的预处理，可以有效地筛选数据(matlab rough set algorithm, mainly used in the pre-processing of the neural network and support vector machine algorithm can effectively filter the data)

這是一個利用butter filter 的bandstop 來濾除原始訊號中有雜訊的方法，先轉為spectrogram觀察雜訊所分步頻帶與能量，再依照要濾除的部分作bandstopa(This is a use of bandstop butter filter to filter out the noise of the original signal has a method, the first step into a spectrogram observation noise and energy of the band, then follow to filter out parts for bandstopa)
