| 摘 要： | 一、引言RC模拟滤波器,是一种低通滤波器。虽然人们对它并不陌生,但把它用于工业控制机的输入部分,并且合理地选用它,也并不是一件容易的事。随着计算机技术的发展,工业用数据采集系统得到了广泛的应用。由于它的输入讯号来自于生产过程中的各种测量仪表,而这些仪表又多安装在充满各种电磁干扰的环境中,

| Abstract: | The usual method of rejection normal mode noise is to use low-pass filters.The commonest kind of them are RC-filters. The paper discuses the sources ofnoise, introduces some calculation forms of single-pole, double-pole and triple-pole RC-filters, and explains how to select RC-filters for the industrial dataacquisition system. |
