Electromagnetic compatibility issues in industrial equipment

The aspects covered by the EMC regulations, in particular European Directive 89/336/EEC, are numerous and often complex. In this article, the authors have tried to summarize the standards recalled by the Directive for industrial and residential equipment and to emphasize some relevant measurement and design problems. The picture is surely vague and incomplete, but one point should be evident: EMC is a real problem and finding solutions which are technically suitable and economically competitive is today's challenge for design engineers.
