Abstract
A bus system for carrying out data transfer between one bus master and a plurality of bus slaves. The bus system includes plural directional couplers which are formed by arranging respective parts of lines drawn from the bus slaves, without being in contact with, in the neighborhood of, and in parallel with a line drawn from the bus master. The line drawn from the bus master to a terminating resistance is wired to be folded. The directional couplers are further formed by arranging parts of the lines drawn from the bus slaves alternatively with respect to a first line part of the line drawn from the bus master ranging from the bus master to a fold of the line drawn from the bus master and with respect to a second line part of the line drawn from the bus master ranging from the fold to the terminating resistance.
