As technology advances, the need to place larger numbers of electrical and electronic systems into automobiles has dramatically increased. To name a few, these systems include Control Area Networks (CAN), safety systems, communications, mobile media, infotainment systems including wireless headsets, DC motors and controllers. The physical size of these systems is greatly reduced because of the size and weight constraints involved with automotive design. These systems may be small, but it does not necessarily mean their electromagnetic emissions are too.
