- 據此實(shí)現的DVF-1型智能數字電壓頻率測量?jì)x的VFC系統,滿(mǎn)度非線(xiàn)性誤差達到了3×10~(-6),遠優(yōu)于NSC公司相同原理精密器件LM331的1×10~(-4)非線(xiàn)性水平。Based on this, the design procedure for the low nonlinearity V/F converter is developed and a simple compensating method is given, which is proved to be successful on the DVM of Model DVF-1. The V/F converter used in the DVF-1 provides a nonlinearity within 3ppm, which is much better than that of LM 331 developed by NSC Company.
