这个主要设计了一个butterworth 滤波器 实现滤波效果(this is used to lvbo and design a butterworth )

局部放电试验所采集的信号中往往混有白噪声、周期干扰信号去除。此处采用常用db系列小波中的db6小波进行9尺度的多分辨分解后，根据白噪声能量特性，估算各尺度的阈值大小，采用硬值进行处理，后进行重构。(Partial discharge test of the signal collected is often mixed with white noise, periodic interference signal removal. Here the use of commonly used wavelet db Series DB6 wavelet carried out in the 9-scale multiresolution decomposition, based on the energy characteristics of white noise to estimate the scale threshold size, the use of hard-value deal, after the remodeling.)

给大家提供一个最基础的simulink仿真的列子 (To provide a most basic simulation simulink Liezi)

说明：  三层bp网络实现三种模式识别，没有使用matlab工具箱，完全自己手写(Three modes of three bp networks to identify, do not use matlab toolbox, completely on my own handwriting)
