摘要
基于RLC串联谐振电路的原教学方案,引入新设计的组合开关,提出新的教学方案,对串联谐振电路的幅频特性研究相关实验教学内容进行了适当扩充,较为全面地展示了串联谐振电路的幅频特性,实现了教学方案的分层设计.在多途径精准确定谐振频率的基础上,实现了回路主要参量的测定,简化了实验操作步骤.
Based on the original teaching scheme of RLC series resonant circuit,a new design of combination switch was introduced,and a new teaching scheme was put forward.The related experimental teaching contents of amplitude-frequency characteristics of series resonant circuit was expanded.The amplitude-frequency characteristics of series resonant circuit were demonstrated systematically and comprehensively,and the layered design of teaching scheme was realized.Based on multi-channel accurate determination of resonance frequency,the measurement of main parameters of the loop was realized,and the experimental operation steps were effectively simplified.
