matlab_DigitalModulation

说明：  有频带方差和谱熵法。自己实现加窗分帧。里面设计傅里叶变换还有矩阵的运算。(speech endpoint detection. frequence_diff and pushang.)

里面是几个小波构造的程序，Daubechies小波基的构造，采用多孔trous算法(undecimated wavelet transform)实现小波变换 。(inside several wavelet construction procedures Daubechies wavelet construction, using porous trous algorithm (undecimated wavelet transform) achieve wavelet transform.)

APFC电路，利用市电220V,将Boost电路的功率因数提高，仿真了电流电压波形(APFC circuit)
