基于数值分析的网络综合实验

Network Synthesis Experiment Based on Numerical Analysis

电路网络知识单纯的课堂讲述只会让学生感觉枯燥,不能激发其学习兴趣,难以取得良好的教学效果。该文以一个平行耦合微带线带通滤波器的设计为线索,将理论教学与工程实例有效结合,以数值分析教学作为出发点,逐渐过渡到电路网络以及实际工程器件的设计制作,实现理论与实践的完全贯通,以激发学生的学习积极性。在整个设计过程中,涵盖了数值分析知识、电路网络知识及微带线滤波器设计原理等,同时使用了数值分析软件、电磁仿真软件和网络分析仪等实践工具,有助于培养学生的学习和动手能力,促进学生科学逻辑思维能力的训练。

Conventional teaching approach makes students felt boring, and cannot stimulate their interest in learning, so the teaching results is not good. In this paper, the design of a parallel coupled microstrip line bandpass filter is used as a clue to combine the theoretical teaching with engineering examples. It starts from the introduction of numerical analysis. Then, the network synthesis will be applied and finally the actual component will be fabricated and measured. In the whole design process, it covers some principles, such as the numerical analysis of knowledge, circuit network knowledge and microstrip line filter design and so on. At the same time, some CAD softwares and measurement apparatuses are also used. It can cultivate the students’ learning and practical ability and promote their scientific logic thinking ability training.
