本文提出了取样技术中一种新概念“多次取样效应”,并以开环取样系统过渡过程为基础,分析线性系统的多次取样效应,推导出多次取样过渡过程的一般公式。该公式表达了多次取样为常3取样的一般形式·即常态取样是多次取样当n=1时的特殊情形。文中利用公式计算了n=1、2、态、n时的过渡过程。同时讨论了阶梯函数波形的演化情况。文中还例举了取样显示中所发现的多次取样的实例。讨论了产生多次取样效应的几种可能性。文章最后给出了实验中的波形照片。
In this paper, we propose a new concept of “multiple sampling effects” in sampling technology. Based on the transition process of open sampling system, we analyze the multiple sampling effect of linear system and deduce the general formula of multiple sampling transition process. This formula expresses the general form of sampling multiple times as a constant, that is, the normal sampling is a special case of sampling multiple times when n = 1. In this paper, we use the formula to calculate the transition process of n = 1,2, n, n. At the same time, the evolution of the ladder function waveform is discussed. The article also cites examples of multiple samplings found in sample displays. Several possibilities for generating multiple sampling effects are discussed. Finally, the article gives the waveform of the experiment.
