Abstract
A liquid ejecting device includes a driving waveform signal generating circuit that generates a driving waveform signal, a modulation circuit that performs pulse modulation on the driving waveform signal to generate a modulation signal, a digital power amplifier that amplifies power of the modulation signal to generate a power amplification modulation signal in the form of a pulse wave, a filter that smoothes the power amplification modulation signal in the pulse wave to generate the driving signal, a connection cable that connects the filter to the capacitive load and is provided such that at least one of the filter and the capacitive load is detachable, a connection line information acquiring unit that acquires connection line information associated with the connection cable, and a frequency changing unit that changes a frequency when the modulation circuit performs the pulse modulation on the driving waveform signal, on the basis of the connection line.
