教材是学校教育、知识传授和人才培养最基本的教育资源.选取2010年以来新出版或再版的8本国际知名电子技术基础教材,重点介绍其编写特色、知识体系和内容更新情况,可以为我国相关教材的编写提供一些参考.同时,结合我国电子技术教学的历史和现状,提出了几点课程改革的建议.
Microcomputer system is unsuitable as a practice platform for "Computer Organization and Interface Technology" learners because of its complexity. In order to solve this problem, the educators have proposed a large number of solutions, such as simulation software, embedded micro-controller, FPGA, etc., but all the existing solutions have certain limitations. This paper presents a practical approach combining simulation software and FPGA platform, which can effectively help students understand the knowledge required for the course. The approach has been in use for undergraduates of the school of electronic information and communications in Huazhong University of Science and Technology for many years, and the outcome is good.

本文针对微处理器发展的多样化给教学带来的困扰,就如何选择合适的教学内容、教学平台、教学方式让学生在有限的教学学时内掌握微处理器相关的计算机原理以及接口设计技术,开设了“微处理器与接口技术”课程.我们将这门课程替换原有“微机原理与接口技术”课程,并在我系数理提高班进行了有益的教学实践,取得了较好的教学效果.
This paper focuses on the problems in teaching process of the electronics technology class foundation courses, which are required for EE and CS undergraduate students. And under the collaborative innovation con-cept, the paper has provided some collaboration methods and measures through knowledge, theory and practice, school-enterprise, curricular and extracurricular, course and competition, studying process, and class teaching and learning in web, in order to explore new ways of teaching reform.
A true random number is combined by software and hardware,with which new random RF protocol can be produced.At the same time,through controlling of RF power,transformation of sender and receiver is completed from public RF protocol to new random RF protocol,and random matching of wireless microphone and receiver is realized.The implementation of project shows that the random RF protocol is a good method to realize random matching of wireless microphone and receiver.
In this paper,a simulation-based teaching method of embedded systems was put forward.The software of hardware simulation and the software of CPU program simulation were integrated.It formed a jointed simulation system,and obtained that hardware experiments were instead by software simulation.Therefore,it will effectively improve the teaching experiment of embedded systems.
从基于RC振荡电路、晶体振荡电路到石英锁相环频率合成电路的无线话筒,目前在多媒体教室应用中仍然是主流。但在多媒体教室密集的教学楼或区域紧凑的教室群,现有技术的无线话筒显然不能满足应用需求。为此,文中进一步介绍了有线(移频)话筒、可调频率无线话筒、红外线无线话筒等过渡性技术,并阐述了收发双方实现任意配对自适应跳频无线话筒的技术方案。最后,通过技术比较表明收发双方都实现任意配对技术功能的无线话筒是目前多媒体教室无线话筒的技术发展趋势。
