摘要
利用 2个特性相同的光电耦合器与集成运算放大器组成反馈电路和输出电路 ,实现了多电源供电系统模拟信号的不共地传输 。
Two photoelectric couplers with the same characteristic and one integration operational amplifer are used to make up circuits of feedback and output,realize the uncoen-ground transmission of analog signals in multi-power supply system,and work out the solution of common-mode interference in the course of signal transmission.
