离散信号卷积的简便运算方法

A Simple Operation Methods of Discrete Signal Convolution

通过对信号与线性系统中离散卷积及其运算方法的分析,研究序列形式的离散信号的卷积运算过程,在图解法基础上提出了较为简便的运算方法———列表法.此列表法与图解法所得结果完全相同,却使运算过程大为简化.

The authors study the convolution operation process of discrete signal of sequence form by analyzing the discrete convolution and the operation methods of signals and linear systems.On the basis of graphical method,they put forward a more simple operation method - tabulation method,which can get the same result as by graphical method but greatly can simplify the operation process.
