Abstract
A demodulator for recording head includes a reference-clock input section to which a reference clock is inputted; a modulated-signal input section to which a plurality of types of modulated signals generated by modulating a plurality of types of recording signals corresponding to a plurality of types of jetting modes of the recording head are inputted; a demodulation-clock generating circuit which generates from the reference clock, a demodulation clock for detecting the timing at which the value of the modulated signal changes; and a demodulator circuit which demodulates the modulated signal to the recording signal by detecting the timing, at which the value of the modulated signal changes, by using the demodulation clock, and the plurality of types of modulated signals have different timings, based on the reference clock, at which values of the modulated signals change, respectively.
