摘要
"数字信号处理"课程中,在定义两个序列的循环卷积时,在时域一般都是依据定义直接进行计算,但是这种方法很繁琐。本文通过分析循环卷积与线性卷积的关系,提出了一个非常简单的用于计算循环卷积的方法。笔者通过具体的计算实例,详细介绍了本文提出的方法。
It is usually directly calculated according to the definition in Digital Signal Processing course when the circular convolution of two sequences is defined. But it is complicated. This paper analyzes the relationship between the circular convolution and linear convolution of two sequences, and proposes a simple method for the former. The proposed method is illustrated by an example.
