离散时间序列卷积和的求法

卷积是“信号与系统”课程中的重要概念。连续卷积与有限长序列的卷积和在文献中给出了多种解法。文中系统介绍了求解一般离散时间信号卷积和的几种方法，包括解析法、列表法、利用卷积和性质求解及应用单位样值信号求解，并通过举例加以说明。最后，对各种解法进行了比较和讨论。

Seeking Methods for Convolution Sum of Discrete Time Series

Convolution is an important concept in ＂Signals and Systems＂ course. Methods for calculating continuous convolution and finite length convolution are given, and several solution methods to the convolution sum of general discrete time series, including analytical method, tabulation method, methods by described in utilizing the properties of convolution sum and applying unit sample are described in detail and illustrated by examples. Finally, comparisons and discussions of the above methods are provided.
