调频收音机原理与制作实验的教学探讨

Teaching Discussion on Principle and Assembling Experiment of Frequency Modulation Radio

介绍了调频收音机的基本原理和实验步骤,在分析学生实验过程的基础上,提出了优化的教学方法.通过实验步骤的分解,要求学生做针对性的技能训练,并独立地完成实验,使得整个实验过程处于有序控制之中,为该实验的优化教学做了较为深入的探讨.

Principle and assembling of frequency modulation radio is an important professional experiment.In this paper,principle and experimental procedures of frequency modulation radio have been introduced in detail.Moreover,based on analysis of students′experimental process,optimized teaching approaches have also been proposed.By decomposing the experimental procedures,students are asked to practice important technique,and to perform the experiment independently.As a result,the experiment is under ordered control,while the proposed approaches are extensively discussed to optimize the teaching.
