关于电子信息工程专业高频实验的改革的关于电子信息工程专业高频实验的改革的探析探析摘要:本文针对本校“高频电子线路实验”教学中普遍存在的问题。从教学内容和教学方法等方面进行了分析研究。对高频电子电路实验教学的现状提出了高频实验教学应采用的方法及手段,提高教学质量,使学生能够尽快适应现代电子线路设计的需要。Abstract: this article for the school teaching of high frequency electronic circuit experiment “common problem. From the aspects of teaching contents and teaching methods are analyzed. For high frequency electronic circuit experiment teaching present situation, proposed the high frequency should be adopted in the experiment teaching methods and means, improve the quality of teaching, enables students to meet the need of modern electronic circuit design as soon as possible.关键词:高频电子线路实验教学方法教学手段Key words: high frequency electronic circuit experiment teaching means teaching method(一) 目前高频电子技术试验课的现状(a) the high frequency electronic technology the present situation http:/www.tshengdong.com/ http:/www.lwjinnuo.com/of the test class高频电子技术是电子信息类专业的重要基础课程,是一门理论性、工程性与实践性都很强的课程,它的内容丰富,应用广泛。该课程的任务是研究高频电子线路的基本原理与基本分析方法,以单元电路的分析和设计为主。其主要内容包括:高频电路的基本知识、高频小信号调谐放大器、高频谐振功率放大器、正弦波振荡器、振幅调制和解调、环形混频器等内容。High frequency electronic technology is a important basic course of electronic and information profession, is a theoretical and physical and practical very strong curriculum, its content is rich, wide application. The course of the task is to research the basic principle of high frequency electronic circuit and the basic analysis method, is based on analysis and design of unit circuit. Its main contents include: basic knowledge of the high frequency circuit, high frequency small signal resonance power amplifier tuned amplifier, high-frequency, sinusoidal oscillator, amplitude modulation and demodulation, annular mixer, etc.随着电子技术的飞速发展,对高频电子技术试验课提出了更高的要求。With the rapid development of electronic technology, the high frequency electronic technology experiment class put forward http:/www.tahsft.com/ http:/www.tajthg.cn/higher request.1.1 教学现状与需求分析1.1 the teaching present situation and the demand analysis当前大部分“高频电子线路”教学仍然沿用较为经典的内容。例如。在功率放大器章节中,动态负载线和丙类功率放大器的分析方法依然是其核心内容,而在目前的射频功率放大器设计中,由于 c类放大器具有非线性特性,所以应用较少,D 类和 E 类放大器已经成为当前设计应用的主流;当前教学中,调制与解调主要以模拟调制(AMFM,PM)方式强调,这些内容有助于理解调制与解调的基本概念,是教学内容中不可或缺的部分;因此,Most of the current “high frequency electronic circuit“ teaching still continue to use the content of the more classic. For example. In power amplifier section, dynamic load line and the analysis methods of class c power amplifier is its core content, and in the present in the design of rf power amplifier, because c amplifier with nonlinear characteristics, so the application is less, class D and E class amplifier has become the mainstream of current design applications; In current teaching, mainly analog modulation of modulation and demodulation way (AM/FM, PM) stressed that the content is helpful to understand the basic concept of modulation and demodulation, is an indispensable part in teaching content; As http:/www.tshengdong.com/ http:/www.lwjinnuo.com/a result,“数字调制”方面的内容和要求在教学大纲中有待加强。“Digital modulation“ aspects of the content and the request needs to be strengthened in the syllabus.随着科技的飞速发展,创新渐渐成为当今的主题。因此。在高频电子线路实验中的创新也变得极为重要。这就需要学生能用所学的理论充分与实际相链接,达到自主创新的目的。With the rapid development of science and technology, innovation has become todays theme. Therefore. The innovation in high frequency electronic circuit experiment also become extremely important. Which requires students to use learning theory with reality adequately link, achieve the goal of independent innovation.如:开展电子设计大赛等相关的活动,不仅激励学生学习的积极性。而且充分的调动了大家对于实验的兴趣。同时,大大提高了学生的动手、动脑能力。Such as: electronic design contest and other related activities, not only inspire the enthusiasm of students learning. And fully mobilize the interest for experiment. , the brain at the same time, greatly improving the students practical ability.1.2 实验设备存在的问题http:/www.tahsft.com/ http:/www.tajthg.cn/1.2 problems existing in the experimental equipment首先,由于设备的使用寿命有限,试验室的设备损坏的程度比较严重,设备的更新和维护问题成为关键。First, since the service life of equipment co., LTD., laboratory equipment is too badly damaged, update and maintenance of equipment become the key problem.其次,再进行高频实验中,试验设备很容易受到干扰,如何解决设备的干扰问题也尤为重要。Second, and then to high frequency experiment, test equipment are quite easily disturbed, is also very important how to solve the interference problem of equipment.最后,就是实验设备的选择问题。现行高频电子线路实验课程中采用的高频电子线路实验箱,将高频实验所需的直流电源、频率计、低频信号源和高频信号源设计成一个公共平台。而且,这种整机实验如果某部分电路或元件被损坏,实验员检修很困难,模块不宜更换,且很难配置。因此,实验器材的选择也要予以考虑。In the end, is the choice of experimental equipment. Current high frequency electronic circuit experiment course of high frequency electronic circuit experiment box, to the dc power supply of high frequency experiment, frequency meter, frequency signal and high frequency signal source design into a common platform. Moreover, the whole experiment if a particular part of the circuit or component http:/www.tshengdong.com/ http:/www.lwjinnuo.com/is damaged, the experimenter maintenance difficult, module should not be replaced, and it is difficult to configu
