Data Acquisition数据获取代码，主要从麦克风获取语音信号，然后real time plot输入信号的时域和频域波形图(Data Acquisition Data acquisition code, mainly for voice signal from the microphone, and then real time plot of the input signal in time domain and frequency domain waveform)

采用鱼群MP算法来对单信源AFSA波达方向估计，可以得到很好的结果(Adopt shoals MP algorithm to single source AFSA doa estimates, you can get a good result )

dc-dc buck电路，仿真效果较好，偏差控制的很小，pi效果不错(DC-DC buck circuit, simulation effect is good, deviation control is very small, PI effect is good.)

说明：  matlab代码，实现神经网络中的BP算法-误差反向传播算法，用于分类，拟合和非线性系统建模等多种问题(An example of BP neural network)

说明：  我们知道，小波变换的一级分解过程是，原始信号分别进行低通、高通滤波，再分别进行二元下抽样，就得到低频、高频（也称为平均、细节）两部分系数；而多级分解则是对上一级分解得到的低频系数再进行小波分解，是一个递归过程。以下是一维小波分解的程序. (We know that a wavelet transform decomposition process is that the original signal were low-pass, high pass filter, and then carried out under the binary sample, we obtained low-frequency, high-frequency (also known as the average, details) coefficient of two parts and Multi-level decomposition is a decomposition of the previous low-frequency coefficients to be further wavelet decomposition is a recursive process. Following is a one-dimensional wavelet decomposition process.)
