Being the DA transmitter which converts the digital signal which is input to the analog signal, on the basis of the relative result in the level relative section and the level relative section which it compares whether or not integral calculus value which the integrator and the integrator which output integral calculus value of the digital signal, to every cycle of fixed period output, became an excess state where it is larger than specified reference value, from integral calculus value, from the feedback section and integral calculus value every of cycle which the integrator outputs, and in the cycle immediately before each one integral calculus value which reduce the value which is decided beforehand, with time resolution under fixed period, the change which is transited in excess stateThe DA transmitter which has with the signal processing unit which forms the analog signal on the basis of the timing occurrence section and the timing signal which form the timing signal with time resolution under fixed period on the basis of the timing information formation department and the timing information which form the timing information of the point, is offered.
