Liquid ejecting apparatus and liquid ejecting head

Abstract

An ink jet printer includes: a drive signal generation unit that generates a drive signal, an ejecting section that includes a nozzle, a piezoelectric element driven by the drive signal, and a cavity that ejects an ink from the nozzle in response to driving of the piezoelectric element, a first inspection signal generation circuit to which a residual vibration signal generated by residual vibration in the ejecting section after the piezoelectric element is driven is input and which generates a pseudo residual vibration signal according to the residual vibration signal, and an inspection unit that determines a state of the ejecting section based on the pseudo residual vibration signal, in which the first inspection signal generation circuit includes a first filter circuit that generates the pseudo residual vibration signal, and the first filter circuit includes a variable resistor element having an adjustable resistance value.
