基本小波函数去噪程序，其中有小波db3、db6和sym8，程序较为基础简单，适合初学者~-Basic wavelet function de-noising procedure

采用db3小波对信号进行六层分解，可以用作容错故障检测的源程序，我做的小论文就用的这个程序，没有错误-Using six db3 wavelet decomposition of the signal can be used as fault tolerance fault detection of the source, I made a small paper on the use of this program, no errors

小波方法进行降噪，阈值函数来完成不同设计，核心程序如下面的所示，使用的小波基有coif5，db3，sym4，bior2.4，haar，rbio-Wavelet method for noise reduction, design to complete different threshold function, the core program as shown below, using the wavelet base coif5, db3, sym4, bior2.4, haar, rbio

语音信号小波去噪 在小波基 db3 下进行一维离散小波反变换 对输出信号抽样点值进行归一化处理-Speech signal wavelet de-noising in wavelet bases ' db3' one-dimensional discrete wavelet transform on the output signal sample point value normalization
