INTRODUCTION

this file has codes that describes how to ccmpute the signal spectrum , the power spectrum, how to calculate the autocorrelation sequence of a signal, how to calculate the autoregressive coeffecients of a signal,and how to reduce the noisy elements in a speech sample.

本程序的性能已经超过其他算法，小波包分析提取振动信号中的特征频率，采用累计贡献率的方法。( This program has exceeded the performance of other algorithms, Wavelet packet analysis to extract vibration signal characteristic frequency, The method of cumulative contribution rat.)
