《高频电子线路》课程“振幅解调”教学策略

TEACHING STRATEGIES OF AMPLITUDE DEMODULATION IN HIGH FREQUENCY ELECTRONIC CIRCUIT

介绍两种常用的调幅信号解调方法,即同步检波法、包络检波法。采用对比教学法帮学生建立振幅解调的完整知识体系。引导学生设计简易二极管包络检波电路并观察解调失真。初步探索在高频电子线路课程中理论、实践相结合的新思路、新途径。

This paper describes two common amplitude demodulation methods, namely synchronous detection method and en- velope detection method. Contrasting teaching methods help students develop a complete knowledge system on amplitude de- modulation, leading students to design a simple diode envelope detector circuit, and to detect demodulation distortion through an oscilloscope. This paper has explored new ideas and new ways of teaching the course of High Frequency Electronic Circuit through the combination of theory and practice
