关于“信号与系统”课程的几个问题

Several Questions about the Course of Signals and Systems

探讨了信号与系统中的三个基本问题 :时域解零输入响应、零状态响应和全响应表达式的写法问题 ,卷积积分的微分、积分性质的运用问题 ,傅里叶变换的微分、积分特性的运用问题。对以上几个容易产生概念性错误的问题进行了深入分析 。

Three basic questions about the course of 'signals and systems' are discussed:the expressions of zero input response, zero state response, and absolute response; the differential and integral characteristics of convolution integral; the differential and integral characteristics of Fourier transform. Several related conceptions and formulas easy to distortion are analyzed deeply. The reasons leading to mistake and the methods to avoid producing the wrong answers are given.
