Abstract: A multipole connector includes a connector body that includes a first end surface and a second end surface; a plurality of contacts that are arranged and led to the first end surface of the connector body; and a ground plate. The multipole connector is connected to a cable in which ground meshes forming external conductors that are to be grounds and core wires that are to be signal lines are insulated from each other by an inner jacket and the outer side is sheathed with an outer jacket. The signal lines are connected to signal line contacts in the contacts, respectively, the ground meshes are connected together on the ground plate, and the ground plate is connected to at least one of the ground contacts of the contacts.

Abstract: 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.

Abstract: 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.
