Background Most of electronics engineers have experienced EMI related issues. It has been understandable and acceptable to complain about the EMI when we have trouble debugging our circuits or equipment. People like to treat it as a black box for this is a good excuse to stop us from investigating what’s going on behind the phenomenon. However, the fact is that with the advances in modern microelectronics, it has been getting more challenging than ever for electronics engineers to eliminate or reduce the EMI caused by higher frequency and higher-degree integration. Meanwhile, the EMC compliance is getting much Background has of understandable and acceptable to complain about the EMI when we have trouble debugging our circuits or equipment.
