摘　　要：针对采用光敏二极管进行光耦合的线性光耦所搭建电路线性输出范围较窄的问题,选用光敏三极管进行光耦合的非线性双路光耦设计电路,并对电路进行了直流分析和低频交流分析。实验证明,该电路扩展了线性输出范围,并能有效地完成信号的采集任务。According to the problem that the output range of the circuit is too narrow, this article designed a circuit which realized linear transmission by applying nonliner optocoupler, and analysized the circuit. It was proved that the circuit extended the output range and could acquire signals effectively.
