Random Processes for Eletrical Engineerging 5th

基于MATLAB软件仿真设计FIR滤波器，然后对噪声信号进行去噪，从而改善语音信号的质量。本文滤波器设计的方法则是采用简单的窗函数（凯撒窗）来设计的，并利用MATLAB作为编程工具完成一些数据的计算以及绘制出去噪前后的时域图和频谱图。通过对比去噪前后的时域图和频谱图，或者通过生成的声音文件，分析说明出滤波器设计的正确性。(The FIR filter is designed based on MATLAB software, and then the noise signal is de noised to improve the quality of speech signal. The method of designing the filter in this paper is designed by using a simple window function (Kai Sachuang), and using MATLAB as a programming tool to complete the calculation of some data and to draw the time domain diagram and spectrum map before and after the denoising. By comparing the time domain and frequency spectrum before and after the noise elimination, or through the generated sound files, the correctness of the filter design is illustrated.)

大致思路说说，就是在外部SRAM里面做了一个大数组[320][240]做了一帧缓冲，所有屏幕相关操作都是在这一帧上面实现的，使用DMA直接丢数据到FSMC接口上，比I/O快多了，然后就是资源的去背问题，所有的图片都是我从手机版上面截图下来的，然后背景色都是0X4DF9，然后因为jpg转换软件的关系，蓝色的背景色会有偏差所以直接判断把0x4df9不显示不可行，后来想到可以用RGB颜色来入手，虽然不是0x4df9但是还是蓝色，所以蓝色分量肯定比红色多，所以做了一个阈值判断(Roughly speaking, a large array [320] [240] is made in the external SRAM to do a frame buffer. All screen-related operations are implemented on this frame. Using DMA to drop data directly to the FSMC interface is much faster than I/O. Then it is the problem of resource backtracking. All the pictures are taken from the top of the mobile version, and then the background color is 0X4DF9. Later, because of the relationship between JPG conversion software, the blue background color will be biased, so it is not feasible to directly judge that 0x4df9 is not displayed. Later, I thought that RGB color can be used to start with. Although it is not 0x4df9, it is still blue, so the blue component must be more than red, so I made a threshold judgment, and then it is the transition between scene and scene.)

Swfoto 1.0 是一款flash(swf)读取图片的容器,可以用于各种网站网页中，用来制作图片切换、焦点图使用，自动读取指定文件夹中的图片并显示，功能特点： 　　图片自动防缩大小，保持比例，不变形 　　图片采用抗锯齿防缩方法，让图片放缩后依然清晰 　　可以定义图片是否有连接 　　方便网页布局，插入任何图片。 　　特别提醒：由于flashplayer9 升级了安全策略问题，所以需要保证所有的的文件（包括swfoto.swf 图片文件）都必须在统一域名下，不能在跨域读取图片了。
