（1）通过MATLAB编程画出输出电场、输出功率传递函数随外加波导两臂相位差的变化曲线；
（2）确定相位调制器、强度调制器的偏置电压；
（3）假设理想条件下强度调制器消光比为20dB，通过MATLAB编程画出消光比曲线随3dB耦合器分光比的变化。（分光比R=0.45:0.05:0.55）(1. For push-pull MZ-LiNbO3 modulator;
(1) The curves of the output electric field and the output power transfer function with the phase difference between the two arms of the external waveguide are drawn by MATLAB programming.
(2) Determine the bias voltage of phase modulator and intensity modulator;
(3) Assuming that the extinction ratio of intensity modulator is 20 dB under ideal conditions, the extinction ratio curve of intensity modulator varies with the splitting ratio of 3dB coupler by MATLAB programming. (Spectrum ratio R = 0.45:0.05:0.55))

第七次课--视频图像DCT处理及水印嵌入_2
说明： 熟悉IIC协议总线协议，采用IIC总线对图像采集传感器寄存器进行配置，并转换为RGB565格式。
利用异步FIFO完成从摄像头输出端到SDRAM 和SDRAM 到VGA 接口各跨时钟域信号的传输和处理。
利用 SDRAM 接口模块的设计，实现了刷新、读写等操作；为提高SDRAM 的读写带宽，均采用突发连续读写数据方式；并采用乒乓操作实现 CMOS 摄像头与VGA的帧率匹配。
利用双线性插值方法实现对图像640×480到1024×768的放大操作。
完成VGA显示接口设计。(Familiar with IIC protocol bus protocol, IIC bus is used to configure the register of image acquisition sensor and convert it into RGB565 format.
Asynchronous FIFO is used to transmit and process signals across clock domain from camera output to SDRAM and SDRAM to VGA interface.
With the design of SDRAM interface module, refresh, read and write operations are realized. In order to improve the read and write bandwidth of SDRAM, burst continuous read and write data mode is adopted, and table tennis operation is used to achieve frame rate matching between CMOS camera and VGA.
The bilinear interpolation method is used to enlarge the image from 640*480 to 1024*768.
Complete the VGA display interface design.)

一组css3特效的banner效果，左右按钮全屏，在支持CSS3浏览器下浏览，动画切换效果十足
如果在不支持CSS3属性的浏览器下，则是从上往下，左右文字分开展示，效果同样不错(A set of CSS3 special effects banner effect, left and right button full screen, in support of CSS3 browser browsing, animation switching effect is full
If the browser does not support CSS3 properties, it is from top to bottom, left and right text display separately, the effect is also good)
