摘要:
许多信号微分出现冲激信号,因而利用微分冲激法将简化此类信号的卷积计算。理论分析了微分冲激法卷积两个时限信号,微分冲激法可以积分一个信号的微分冲激与另一个信号的卷积结果,也可以卷积一个信号的微分冲激与另一个信号的积分,例题阐述之。微分冲激法的应用是为了学生更好地掌握卷积知识。

Abstract:
Impulse signals appear while many of the signals are differentiated, thus taking advantage of Differentiation Impulse Method will simplify calculation of the convolution for this kind of signals. Convolution of two time-limited signals with Differentiation Impulse Method is theoretically analyzed, Differentiation Impulse Method can either integrate the convolution result of one signal's differentiation impulse and the other signal, or can it convolute one signal's differentiation impulse and the other signal's integration, which is demonstrated by the examples. Differentiation Impulse Method is applied for the students to better grasping the knowledge of convolution.
