摘要：In a digital-to-analog converter comprising a pulse-width modulation signalgenerator for generating a pulse-width modulation signal by pulse-width modulating anactual set value with a count value, and a low-pass filter for removing a high frequency
component of the pulse-width modulation signal so as to output an analog signal, adifference between a current target digital value and a previous target digital value aremultiplied by a coefficient determined from a time constant of the low-pass filter and acycle of the target set value, and the multiplied value is added to the previous target setvalue so as to calculate the actual set value.
