Abstract
A compensation method compensates for a length offset between a first transmission line and a second transmission line of a differential signal transmission. The compensation method includes calculating a transmission speed of a first signal in the first transmission line, measuring lengths of the first and second transmission lines, calculating a transmission time of the first signal in the first transmission line, and calculating a relationship between permittivity values of the first and second transmission lines. The compensation method further changes the permittivity values of the first and second transmission lines according to the relationship.
