It is based on the principle of vector summation. Using precision rectifier, the AC signal transfers into DC signal.
它基于矢量求和的原理，使用精密的整流器，把交流信号转换成直流信号处理。
For AC voltage measurement, an RMS converter circuit or a precision rectifier circuit convert the AC signal into a DC voltage.
对于交流电压测量﹐利用有效值转换电路或精密整流器电路将交流信号转换成直流电压。
Deletion of C2 removes the averaging function and provides a precision full-wave rectifier, and deletion of C1 provides an absolute value generator.
如果去掉C2，电路就不再具有平均值滤波功能，只是一个精密全波整流器，如果去掉C1，电路就变成求绝对值的电路。
