这是一个MATLAB编写的进行低通滤波的函数(This is a MATLAB prepared to carry out low-pass filter function)

说明：   该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时，由于180K电阻的作用，使四个开关的控制端为低电平，开关断开，LED 不发光。随着水位的增加, 由于水的导电特性，使得IC的13脚为高电平，S1接通，LED1点亮。当水位逐渐增加时，LED依次发光指示水位。水满时， LED4发光， 显示水满。同时T1导通， B发出报警声，提示水已满。不需要报警声时，断开开关K即可。 (The circuit consists of a four-way analog switch integrated circuit CD4066 core composition. Within each circuit to control four separate digital or analog signal transmission in the switch. When the tank water, the role of the 180K resistor, so that the four low-side switch control, switch off, LED does not light. As the water level increases, the electrical properties of water, making the IC' s 13 feet high, S1 connected to, LED1 lights up. When the water level gradually increased, LED turn light level indication. Is full of water, LED4 LED display full of water. At the same time conducting T1, B alarm will sound, indicating that the water is full. Do not need to sound the alarm when the disconnect switch K can be.)

采用小波去噪的方法对语音信号进行分解和重构，进而提取有效成分，实现信号的去噪(Wavelet denoising method of voice signal decomposition and reconstruction, and then extract the active ingredients, for signal denoising)

本m文件可以用于求解非线性方程，通用性好，容易上手(nonlinear equation solver)

STBC MIMO 通信的代码，模拟了不同SNR下的BER。代码中，有注释说明(STBC MIMO communication code to simulate the BER in the SNR. Code, there are explanatory notes)

能够有效比较FAN和TDOA和泰勒级数展开法三种不同算法在三维定位的优劣性！(Can effectively compare FAN and TDOA and Taylor series expansion method in three different algorithms in three-dimensional positioning and inferiority!)

说明：  NMF及其后续的各种方法，还有ICA的比较方法，(NMFand the expand algorithms ,compare with ICA,)

三重BOOST升压电路仿真，电压电流纹波小，效果较好(Three BOOST boost circuit simulation, voltage and current ripple is small, the effect is better.)
