Claims (1)
し、得られた重畳信号を周波数信号に変換すると共に、
前記直流バイアスに対して正側半サイクルの周波数信号
の積算値と負側半サイクルの周波数信号の積算値との差
を順次前記交流信号のデジタル値とするようにしたこと
を特徴とするアナログデジタル変換方式。A DC bias is superimposed on an AC signal represented by an AC peak value, and the resulting superimposed signal is converted into a frequency signal.
The analog/digital device is characterized in that the difference between the integrated value of the frequency signal in the positive half cycle and the integrated value of the frequency signal in the negative half cycle with respect to the DC bias is sequentially set as the digital value of the AC signal. Conversion method.
