Abstract
A printed circuit board (PCB) assembly includes a PCB having and a ferrite attenuator. The PCB includes input/output signal paths for carrying signals to and from the PCB, power paths for conducting power to the PCB, and ground paths for connecting the PCB to a ground level. The ferrite attenuator surrounds the input/output signal paths, the power paths, and the ground paths. The PCB assembly is preferably used in a system, such as a computer system, where the ferrite attenuator suppresses electromagnetic interference (EMI) generated in the system.
