ABSTRACT:
In an AC signal generating apparatus a digital sine wave signal of a set frequency, generated by a digital sine wave signal generating part, is converted by a D/A converter to an analog sine wave signal and is then output. The output sine wave signal is converted by an output detector to a voltage mean value, and the difference between it and a reference value is obtained by a comparator. The difference is negatively fed back, as a reference voltage, to the D/A converter to control its conversion gain so that the difference may approach zero. Thus, a highly accurate sine wave signal is obtained.
