摘要
卷积是"信号与系统"课程中最重要的运算之一,参与卷积运算的函数是多种多样的,可能是有始的、有终的,也可能是时限的或无时限的,卷积可能存在也可能不存在。本文对各种场合下卷积的运算规则进行了归纳,并探讨了卷积的存在性以及它与卷积性质之间的关系。
Convolution is one of the most important operations in Signal and System course.The functions related to convolution operation are variable.Some of them have initial or terminal time,time-limited or time-infinite.Convolution in them may exist or not.The paper introduces the convolution operation rules in different fields,discusses the existence and the relation between convolution existence and property.
