电子仪器干扰与屏蔽

电子仪器设计、生产过程中,抗干扰问题是线路设计者和结构设计者同时会遇到的重要问题。本文主要阐述了在作为结构设计者怎么解决和抑制干扰问题。干扰来自仪器的内部和外部,一种仪器既可以受到自身的干扰,同时也可以干扰别的仪器。消除和减弱这些干扰,在线路设计中可用滤波器、去耦电路等等。而在结构设计上就要进行屏蔽设计,用屏蔽来消除干扰。

Anti-interference and Shielding of Electrical Instrument

The circuitry designer and structure designer all encounter the intractable problem of anti-interference in electrical instrument designing and manufacturing. The paper describes how to resolve and restrain interference as structure designer. The interference comes from inside and outside of instrument. An instrument may interfere itself and other one simultaneously. Eliminating and weakening interference may use filter and decoupling circuit in circuit design. Shielding design must be adopted in structure design, Shielding design may eliminate interference.
