一种连续信号卷积的代数方法探究

《信号与系统》是现代信息科学的基础,初学者普遍感觉较难学懂。《信号与系统》课程的基础和灵魂便是卷积。卷积运算的难点在于确定卷积积分的积分限和在相应区间上的被积信号。卷积运算的本质是定积分计算。如何将卷积运算转化为大家熟悉的定积分运算,是文中探讨的核心思想。多数教材基于几何思想采用图像法计算卷积,文中对一种计算连续信号卷积的代数方法进行了探究。

Algebraic Method of a Continuous Signal Convolution to Explore

The course of signals and systems, beginners generally feel more difficult to learn. Convolution is the basis and soul of signals and systems. Convolution operation difficulty is to determine the convolution integral in the integral limit and in the corresponding interval on the by product of the signal. As long as we find the right way, stone can crack. Convolution operation is the nature of the definite integral calculation. How to transform the convolution operation familiar with definite integral operation for us？ This is we want to explore the core idea. Convolution is obtained by using the image method on general books. This is a kind of geometrical ideas. This paper is of a continuous signal to calculate the convolution of the algebra method.
