复化三点Gauss-lengend公式求pi，有小波分析的盲信号处理，本科毕设要求参见标准测试模型，采用了小波去噪的思想，基于matlab GUI界面设计,采用加权网络中节点强度和权重都是幂率分布的模型，FIR 底通和带通滤波器和IIR 底通和带通滤波器。- Complex of three-point Gauss-lengend the Formula pi, There Wavelet Analysis Blind Signal Processing, Undergraduate complete set requirements refer to the standard test models, Using wavelet denoising thought, Based on matlab GUI interface design, Using weighted model nodes in the network strength and weight are power law distribution, Bottom-pass and band-pass FIR and IIR filter bottom pass and band-pass filter.
