Abstract

Noise sources and fundamental mechanisms leading to radiated emissions from printed circuit boards (PCBs) have been analyzed. The use of photoelectric couplers at the input and output interfaces between PCBs and of image planes on the PCBs reduces common-mode radiation; the effectiveness has been proved to comply with GJB151A-97 EMI limits.
