摘要： Provided is a signal transmission circuit capable of realizing the same effects as those in a conventional manner that employs a complicated circuit by using no complicated circuit, that is, by a simple circuit. The signal transmission circuit includes: a transmission path having a first impedance; a terminating resistor having a predetermined resistance; a transmission path having a second impedance, which is connected to the transmission path and the terminating resistor, the second impedance being higher than both of the first impedance and the predetermined resistance; and an input buffer for receiving a signal at a connection portion of the transmission path and the transmission path.

摘要： When a change of an output signal is detected by an output-signal-state-change detector, a continuous-change performing part controls an output impedance changing part, which is provided between an output buffer and a signal line, so as to continuously change an output impedance from low impedance to high impedance, at the changing timing of the output signal.
