以一条主线两个重点贯串"信号与系统"课程教学

提出以一条主线两个重点贯串“信号与系统”课程教学的理念，揭示信号的10种时域基本变换与运算，可以将信号与系统科学纷繁的知识模块，珠玑串线式地展现出来；强调突出系统的单位冲激响应，信号的卷积积分两个重点分析与处理方法；在数学解析过程和引出结论时，注重阐述信号与系统分析中强调物理含义的教学方法。形成总体上把握课程讲授与学习的主线和重点，宏观上举重若轻，微观上举轻若重的教材、教法处理思路，收到了较好的教学效果。

Teaching Study on the Course of "Signals and Systems" by One Trunk Line and Two Emphases

In this paper a teaching idea about the course of "Signals and Systems" by 'One Trunk Line and Two Emphases' is presented. The knowledge modules of signals and systems course, can be linked one trunk line in series by 10 basic handle skills of time domain transformer and domain operations of signals. Stress extruding into two main points of the unit impulse(sequence) response and the convolution integral(sum). In the process of resolution, and while the conclusion been educed, emphasize giving the physics explain about the signals analysis and the systems analysis. So that, holding the trunk line and emphases of the teaching and studying signals and systems course in the mass, can get hold of better instructing effect.
