Abstract:
Disclosed herein is a signal output circuit for outputting a signal onto a transmission line having a given transmission characteristic, the signal output circuit including a drive circuit adapted to drive an input signal by a current; and an output resistor which is connected to an output stage of the drive circuit and capable of adjusting the output signal waveform according to its resistance, wherein the drive current of the drive circuit and the resistance of the output resistor are variable.
