摘 要
《随机信号分析》是通信工程专业基础课中理论性较强的一门重要的核心课程，它与后续课程的学习有着密切关系。由于课程内容理论性强，概念抽象，学生普遍存在着学习理解困难问题。随着计算机多媒体CAI技术的发展，为上述问题的解决提供了可能。为此，我们根据教学大纲的要求，对课程重点内容，利用文本、图形、图像、动画、视频等人们熟悉的媒体信息。
多媒体课件的制作方法较多，如使用PowerPoint制作课件，使用Authorware或方正奥思制作课件，使用Word, FrontPage制作课件，可以使用Flash Mx制作课件，还可以使用几何画板制作课件等等。大部分教师一般使用PowerPoint制作课件，主要是因为用PowerPoint制作课件简单易学，处理方便，对于要求不高的一般课件，用PowerPoint很易上手。但用PowerPoint制作出来的课件质量一般不会很高，特别是对于课件中如有声音、视频、动画的要求，PowerPoint就显得功能不太强了。Authorware提供功能强大的多媒体集成解决方案，它能够将文字、图形、动画、声音及视频集成在一起，并实现交互性的训练与教学。其创作的作品成本比阅读式训练与集中式教室教学低且能获得更佳的教学效果。
本文主要论述CAI技术以及研究用Authorware7.0设计《随机信号分析》课件的相关方法及使用技巧。目的在于充分利用多媒体CAI的特点，补充现有教学的不足，促使学习者实现有效的学习。

《The random signal analyze 》the lesson piece of the course design
Take off to want
《The random signal analyze 》BE correspond by letter engineering an important core course with stronger theories in the professional foundation lesson, it is curricular with follow-up of the study have near concern.Because the course contents ories is strong, the concept is abstract, the student is widespread to exist a study to comprehend a difficult problem.Along with calculator multi-media CAI technical development, resolved to provide a possibility for the above-mentioned problem.For this, we request according to the syllabus, making use of the text this,sketch,picture,animation,video frequency to wait for someone to the course point contents acquaint with of medium information.
The creation method of the multi-media lesson piece is more, such as the usage PowerPoint manufacture the lesson piece, usage Authorware or square positive the 奥 think manufacture the lesson piece, the usage Word, FrontPage manufacture the lesson piece, can use the Flash Mx manufacture lesson piece, can also use several drawing board manufacture the lesson piece etc..Greatly parts of teachers use the PowerPoint manufacture lesson piece generally, mainly is because of using the PowerPoint manufacture lesson piece in brief easy to learn, the processing is convenient for requesting the not high general lesson piece, using PowerPoint to start very easily.But uses the lesson piece that the PowerPoint creation come out quality generally not very high, especially for the lesson piece if have the request of the voice,video frequency,animation, the PowerPoint seems to be function not that strong.The Authorware provides the function strong multi-media integration solution, it can integrate the writing,sketch,animation,voice and video frequency together, and carry out to hand over with each other sexual training and the teaching.The work cost that it create is lower than the reading type training and teaching in concentrated type classroom and can acquire better teaching result.
This text mainly discusses the CAI technique and research to use Authorware7.0 designs 《the random signal analyze 》the related method of the lesson piece and usage technique.The purpose lies in well a characteristics of make use of the multi-media CAI, adding the shortage of the existing teaching, urging a valid study of the learner realization.
