摘要

An analog-digital conversion circuit apparatus connectable to a microcomputer for measuring electric voltage and current of a vibrator of an ultrasonic wave oscillator is disclosed. An analog high-frequency wave voltage value signal and an analog high-frequency wave current value signal acquired from a vibration system are alternately input to a conversion-transmission section. A digital high-frequency wave voltage value signal and a digital high-frequency wave current value signal, which have been converted in the conversion-transmission section, are transmitted to the microcomputer for various uses connected with the electric voltage and current of the vibrator of the ultrasonic wave oscillator.
