Abstract
A liquid ejecting apparatus includes a reference drive signal generation section that generates an analog reference drive signal, a signal modulation section that modulates the reference drive signal to generate a digital modulation reference drive signal, a signal amplification section that amplifies the modulation reference drive signal to generate a modulation drive signal, a signal conversion section that converts the modulation drive signal to an analog drive signal, and a liquid ejecting section that ejects a liquid in response to the drive signal. A sum of a resistance value of a reference drive signal transfer line and a resistance value of a drive signal transfer line is smaller than a sum of a resistance value of a modulation reference drive signal transfer line and a resistance value of a modulation drive signal transfer line.
