The invention is directed to the provision of a circuit board mounted with a plurality of circuit components connected via a transmission line. The circuit components mounted on the circuit board includes at least a signal processor for processing a signal, a driver for transmitting the signal, and a receiver for receiving the signal. The driver includes a basic buffer, which is always on, and at least one control buffer, which can be individually controlled on and off, and which is connected in parallel with the basic buffer, and the output impedance of the basic buffer is set higher than the characteristic impedance of the transmission line. |
