<p>PROBLEM TO BE SOLVED: To provide an insertion method of a damping resistor, capable of performing an effective noise countermeasure if a position capable of inserting a noise countermeasure component is restricted.SOLUTION: A resistance value Rd of a damping resistor 4 is determined to satisfy the relationship of Rout+Rd<Z0+Z1, where Rout is an output resistance value of a driver 1, Rd is a resistance value of the damping resistor 4, Z0 is a characteristic impedance of a transmission line 3 from an output terminal of the driver 1 to a position where the damping resistor 4 is inserted, and Z1 is a characteristic impedance of the transmission line from the position where the damping resistor 4 is inserted to an input terminal of a receiver 2.</p> |
