DDS 波形发生器的核心组件是蓄能器。蓄能器是一个正在运行的计数器，将值存储到当前阶段生成波形。蓄能器更新和累加器增量值确定生成波形的频率速率。如果蓄能器每秒和累加器增量更新 360 倍的例子是一个学位，然后生成的频率是 1 Hz （每秒 360 度）。当蓄能器相位值达到最大 （360 度） 它滑过和 0 度时再次启动。为了更准确地代表相位值蓄能器通常使用 32、 48 或 64 位计数器。在 32 位累加器的阶段值具有一个范围从 0 到 4294967295，代表的参考波形或 0 到 360 度的一个完整周期。 累加器 (阶段) 的当前值用于参考波形来确定下一个输出值的查找表中执行查找操作。查找表包含一个周期的波形生成，通常包含 1024年到 8192 采样点所代表的波形。 因为累加器的值通常有很多决议比参考波形，由样本，数目有限的查找操作也可以执行两个样本中的参考波形之间的内插。这基于累加器的值在额外的分辨率进行并返回生成的信号中一个更准确的更新值，提供了更好的频率控制和较少的谐波失真。

想不想体验一下WINCE，照下面的步骤，你完全可以在你的台式机上运行它。第一步，文件拷贝。你需要拷贝几个必须的文件，nk.bin（WINCE的系统），loadcepc.exe（WINCE加载程序），config.sys（WINCE加载必须的设置），autoexec.bat（没有也行，有了更方便）。例如你把nk.bin和loadcepc.exe拷贝到c:cesys。Config.sys和autoexec.bat需要拷贝到dos启动盘上。第二步，启动到DOS。可以从WIN98下启动到DOS，或者做一个WIN98启动盘进入DOS，或者做一个DOS6.22的启动盘，进入DOS。。。随便你了。第三步，进入到c:cesys，执行loadcepc加载nk.bin。关于loadcepc的具体指令格式，如果你感兴趣，键入loadcepc /?，看看文档，如果你不想费劲，直接键入以下指令：loadcepc /l:800x600x16 nk.bin 。。。。。。 CE系统起来了吗？祝你试用愉快。-Want to try WINCE, following steps list below, you can enjoy it: first, copy files. you should copy nk.bin,loadcepc.exe,config.sys,autoexec.bat(optional). For example, you should copy nk.bin and loadcepc.exe to c:cesys and copy Config.sys, autoexec.bat to DOS bootup disk. Second, run in DOS, you may run into DOS from Win98 or boot from WIN98 bootup disk or DOS6.22 boot disk, as you like. Third, turn to directory c:cesys, execute loadcepc, load nk.bin. If you interist in all command format of loadcepc, type "loadcepc /?" and enter to read document. If

两个乒乓球队进行比赛，各出3人。甲队为a,b,c三人，乙队为x,y,z三人，已抽签决定比赛名单。有人向队员打听比赛的名单，a说他不和x比，c说他不和x,z比，请编程序找出三队赛手的名单。-Two table tennis team competition, each person 3. A team for a, b, c three B teams for the x, y, z three, has decided to match the list of drawing. It was asked to match the list of members, a said that he did not and the x ratio, c said that he did not, and x, z ratio, the procedure is requested for three teams racing to find the list.

Mobile手机录像，获取源数据是WMV9格式，输出格式为ASF Requirements: Visual Studio 2005, Windows Mobile 5.0 Pocket PC SDK, ActiveSync 4.0.-Feature Area: Video capture Description: This sample provides the basic video capture functionalities: It captures and encodes video in a WMV file, and captures and encodes an image in a jpeg file. Usage: Build and deploy using Visual Studio 2005. Relevant APIs/Associated Help Topics: ICaptureGraphBUilder2 Assumptions: Your device needs to have a video capture driver installed (the emulator ships with a null capture driver). The video will be saved to the root of your device to "video1.asf". The still picture will be saved to "test.jpg" If you wish, you can change these hardcoded values in the code for the files to be saved to a different location. Requirements: Visual Studio 2005, Windows Mobile 5.0 Pocket PC SDK, ActiveSync 4.0.
