EMC指某電子設備既不干擾其它設備，同時也不受其它設備的影響。電磁兼容性和我們所熟悉的安全性一樣，是產(chǎn)品質(zhì)量最重要的指標之一。安全性涉及人身和財產(chǎn)，而電磁兼容性則涉及人身和環(huán)境保護。
All electric devices or installations influence each other when interconnected or close to each other, e.g. interference between TV sets, GSM handsets, radios and nearby washing machine or electrical power lines.
The purpose of electromagnetic compatibility (EMC) is to keep all those side effects under reasonable control.
