By means of the 3Ds Max and Flash software ,this system reappeared the structure of various automobile parts and their working principle and moving mode,which made the teaching more vividly and lively; Using Goldwave and LAME MP3 Encoder audio-frequency software effectively compressed the system audio media document, so it could reduce the overall system possessive amount; Many kinds of alternately responsible types such as the button,hot spot,text entry and so on,and the function of jumps transfers and link including the hypertext link,goto sentence, navigation icon had been used ingeniously and comprehensivly,which was more helpful to complete successfuly in the interactive design .In order to realize the network publishing of the course soft,source program was optimized on the base of facing to the CD-ROM package.

在系统设计过程中，利用3Ds Max和Flash等动画设计软件虚拟再现了汽车各部件的结构、工作原理和运动方式，使教学更加生动、活泼；利用Goldwave、Lame图形界面Mp3压缩器等音频处理软件有效压缩了系统中的音频媒体文件，进而减少了整个系统的磁盘占有量；巧妙而综合地利用了按钮、热区域、文本框等多种交互响应类型和超文本链接、goto语句、导航图标等跳转链接功能，成功的完成了本系统的交互设计；在面向CD-ROM打包发布的基础上，对源程序进行优化处理，实现了课件的网络发布。

Bubble function is a band pass filter in the frequency domains, while it can't have the ability to adjust bandwidth of filter.

Bubble函数在频域里相当于一带通滤波器，它可以反映不同的时域、频域特性，但它不具有调节带宽的功能。

The filters require close component matching to guarantee that carrier and single-sideband suppression—key measures of quadrature-modulator ideality—do not degrade as a function of baseband frequency.

滤波器需要匹配精密器件，确保载波和单边频带抑制——理想积分调制器的关键——作为基带频率不能降级。
