这里的DDS(直接数字合成)是我在MATLAB中用Simulink基本模块搭建起来的模型,仿真DDS信号的产生,并有一个M文件实现与模型同等的功能,MATLAB爱好者一定不要错过(I build the DDS model using simulink basic model to simulate the DDS source, associated a M file realizing the same function as the model,and,the MATLAB lovers must not miss)

说明：  matlab经典算法，大家支持一下，很有用的啊，哈哈哈(matlab classical algorithm, we support the look, very useful ah, ha ha ha)

已知一个二自由度机器臂的关节长度，给出一个圆形轨迹，让机器臂随轨迹移动。前提是轨迹在机器臂的工作空间内。(Known length of a two degree of freedom robotic arm joints to give a circular path, so that the robotic arm to move with the trajectory. The premise is the trajectory in the workspace of the robotic arm.)

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.)

说明：  输入一个数判定能否开平方，能就开平方，不能就退出(Enter a few decide whether to open the square, to the open square, can not quit)

THIS PROJECT SIMULATION DC/DC BOOST CONVERTER, BUT IT IS NOT SIMPLE, THIS CIRCUIT ADD RESNANT CIRCUIT TO IMPROVE EFFICIENCY AND DECREASE IN LOSSES, WITH SIMULATION YOU CAN SEE HOW YOU CAN MEASURE THE EFFICIENCY.
