Patent ID: 8212863

Claim:
A signal output board comprising: a drive signal generation section configured to generate a drive signal for an electronic device; an inverse signal generation section configured to generate an inverse signal by inverting a phase of the drive signal from the drive signal generation section; a first signal transmission line portion configured to transmit the drive signal from the drive signal generation section; a second signal transmission line portion configured to cancel noise emitted by the first signal transmission line portion by transmitting the inverse signal from the inverse signal generation section along at least a part of the second signal transmission line portion arranged in parallel with and adjacent to the first signal transmission line portion; an output end portion configured to output the drive signal transmitted by the first signal transmission line portion to an outside; and an equivalent load section including a load equivalent to a transmission path for the drive signal from the output end portion to the electronic device, the equivalent load section being connected to an end portion of the second signal transmission line portion.
