| Abstract;In recent years, the EMI has become a social problem. What is required of each equipment is to raise its ability of suppressing EMI emitted from itself and removing EMI coming from outside, i.e. ability of EMC (electromagnetic compatibility). The disigner must fully understand the standard on EMC before designing, but it is not easy. Here, regulations on EMI in foreign countries are described, and it is proposed, as the measures for EMC, to challenge at first to EMI which may have influence on others. And, then, the propagation route of EMI and method of measurement of EMI (antenna, location of measurement, etc.), are explained. |
