Abstract
Noise frequency generated from a circuit is determined. The distance between two arbitrary lines of a plurality of power feed lines or a plurality of power return lines extending parallel to each other is determined on the basis of the determined noise frequency in question. The distance between jumper lines for bridging the two arbitrary lines is determined on the basis of the noise frequency, thereby suppressing emitted noise which can be generated on a printed circuit board.
