Abstract:
A drive circuit includes a duty cycle adjusting circuit that changes the duty cycle of a first signal; and a calculating circuit that with respect to signals that include the first signal for which the duty cycle has been adjusted and a second signal having a phase and amplitude that differ from that of the first signal, performs any one of subtracting one of the signals from the other signal and adding the signals.
