数字合成交流电压标准的原理是很好的建立。本文介绍了一种新的交流电压标准,它采用可溯源的直流电压标准作为输入,并产生等效有效值电压的交流输出,其不确定度为1 /spl μ/V/V。该系统使用具有所谓的脉宽调制器(PWM)数模转换器(DAC)的数字合成来工作。
The principle of digitally synthesized AC voltage standards is well established. This paper describes a new AC voltage standard which uses a traceable DC voltage standard as an input and produces an AC output at an equivalent RMS voltage to 1 /spl mu/V/V uncertainty. The system works using digital synthesis with a so called Pulse-Width Modulator (PWM) Digital to Analog converter (DAC).
