摘　　要：一阶电路响应实验是电路分析中的经典实验。从该实验出发,由所得波形特征引导出一阶电路响应的理论推导方法,通过引入卷积概念,推导理论结果,设计研究性实验加以验证。该探索过程旨在搭建“电路分析”和“信号与系统”课程间的桥梁,为学生提供从识记、理解知识到运用、分析并综合所学的思路,拓展发散性思维意识,提高实践创新能力。First-order circuit response experiment is a classic experiment in circuit analysis course.On the basis of the experiment,a theoretical derivation method of first-order circuit response is proposed based on the obtained waveform characteristics.The concept of convolution is introduced to deduce the theoretical results,and research experiments are designed to verify the theoretical results.The exploration process aims to build a bridge between Circuit Analysis and Signal and System courses,provide students with ideas from memorizing and understanding knowledge to applying,analyzing and synthesizing what they have learned,expand students′divergent thinking consciousness,and improve their practical innovation ability.
