传感器接口电路的抗干扰技术及其应用

Study of Anti-Interference in Interface of Sensors

分析了传感器接口电路常见的干扰及其影响 ,并讨论了滤波、屏蔽、接地、双绞线传输、隔离等抗干扰技术。最后以一个强电测试系统为实例 。

This paper analyses usual interference and its effects, and discusses anti-interference techniques such as filtering, shielding, grounding, transmitting in twisted-pair and isolating. At last,an actual testing system is illustrated, in which some anti-interference techniques are applied to improve the testing accuracy.
