Abstract
A signal transmission system has a response time of a signal transmission line which is set approximately equal to or longer than the length of a transmitted symbol. More specifically, terminal resistance is set larger than the characteristic impedance of the signal transmission line, driver output resistance is set to a large value, or a damping resistor is provided in series with the signal transmission line. With this configuration, signal power can be reduced drastically.
