信号与系统课程是电子信息类专业的核心基础课程,在各种经典教材中都采用冲激响应匹配法求解微分方程零时刻的跳变值。本文分析了冲激响应匹配法求解跳变问题存在的问题,提出了一种应用laplace变换求解跳变问题的新方法,简述了此种方法的原理和求解过程。多年的教学经验表明这种方法更简单,更易让学生掌握。%Signals and systems course is a core course of electronic information majors.In a variety of classic materials impulse response matching method is used to solve the skipping result of differential equations when in zero. This paper analyzes the problems existing in the solving of skipping problem utilizing impulse response matching method,and proposes a new method to solve skipping problem based on laplace transformation together with its theoretical reference and solving process. Many years＇ teaching experience shows that this method is more simple and easier for students to grasp.
