摘要
与硬件方法相比,软件抗干扰技术具有其独特的优点.本文介绍的低通数字滤波器是排除高频干扰的有效工具、文中详细论述了一种非递归型数字滤波器的设计方法,并附有应用实例.还介绍了几种克服工频干扰及随机干扰的软件抗干扰措施。
The technique of software ami-interference has its distinctive advantages compared with hardware method. The low-pass digital filter is an effective tool to eliminate high-frequency interference and a kind of nonrccursive digital filter is described in detail, including its design method and examples given. Besides, several other measures of software anti- interference are also introduced to prevent the industrialfrequency and random interferences.
