模拟量光电隔离电路

光电隔离是系统抗干扰的一种重要措施。但模拟量光电隔离却一直没有得到很好地解决。本文利用Ｖ／Ｆ和Ｆ／Ｖ转换技术巧妙地解决了这一问题。实验证明，该电路具有输入电压范围宽，线性度好，准确度高的优点。

Simulated Measurement Photoelectric Isolated Circuit

Photoelectric isolation is an important measure for resisting the interferences of electricsystems,However,the simulated measurement photoelectric isolation problem has not been well solvedyet.This essay reports the solution of this problem ingeniously by using the V/F and F Vtransformation technique. It has been shown in practice that the resultant circuit has many advantages,e.g.,the input range of voltage is wide,the linearity is good and the accuracy is high.
