There can be various EMC expert systems developed for analyzing the PCB. The algorithms used to predict possible radiated emissions problems from a printed circuit board have been presented. From accuracy point of view, the expert system approach is approximately equal to human EMC expert with a through knowledge of the board and a calculating aid. The algorithms also make assumptions and approximations about how the board will interact with the rest of the system.
