重叠保留法是计算一个短序列与一个无限长序列线性卷积的有效方法。就我们所知，多数《数字信号处理》教材详细叙述了重叠保留法的步骤，有些教材还从线性卷积与循环卷积的关系出发给出了重叠保留法的原理，笔者认为这种解释不够清楚、也不够严谨。本文给出了一个较为严谨而准确的证明。

The overlap save method is efficient for calculation of the linear convolution of a short sequence and a very long or infinite sequence. As far as we know, many textbooks on digital signal processing describe the step of the overlap save method, while some textbooks discuss it from the relationship between circular convolution and linear convolution, but careful analysis shows that the discussion is not very clear and concise. A concise and precise proof is made in this paper.
