EMC Design Practices: Defining the Problem - Part 1 in a Series

摘要

Some people believe that EMC-relatef problems are rare and that EMC engineers can exorcise the demons causing malfunctions in various electronic systems. It's not that way at all. Any electronic system can be thought of as a collection of EMC problems waiting to happen. These may occur from within the system, the system may cause another to malfunction, or the system may malfunction because of the sur- rounding electromagnetic ambient. These emissions or susceptibility problems result from unwanted radiated RF energy or from RF energy conducted on power, control, and signal lines (Figure 1).
