At present, the world is undergoing a revolution of science and technology in which the development of the science and technology of information is the mainstream. The society of human beings is now transferring the era of Industry into the era of Information. After entering the 21st century, the multimedia has been developed better and better along with the development of the Internet. The rise of Computer-aided instruction (CAI) is the most fruitful revolution of information in the educational circle, the media technology have promoted the application of the CAI greatly. People are attaching importance more and more to the multimedia CAI and its prominent characteristics such as its mutuality, its integration, its visualize and its self-adaptation. Multimedia will not only play an important part in the information market, but also has a great influence on the mass media and the learning environment for human beings. This article made a multimedia courseware of circuit and electronics by using the multimedia creation tool-Author ware. And it developed a signal analyzing chart which has animation effect by using the multimedia technology and thus made the courseware become more vivid and visual. It takes the ideas of software engineering and C programmer which were learned before as its overall guidelines for designing. It also made the “studying content” module and the “difficulty and keystone” module. The “studying content” module is especially used for assisting teachers to accomplish the teaching task efficiently. And its characteristics are the followings: it has quintessential content and its key points are popped out; its interface is rich but not disorderly and has strong mutuality; it is easy to use it. The “difficulty and keystone” module conducted a dynamic simulation which is aimed at the difficult points of this course. The dynamic effects are more close to people's thought and enable student have better understanding and mastery of them than ever.
