摘要
简要介绍新型线性光耦隔离器件HCNR201工作原理;详述在实际应用中由于各种因素影响输入信号与输出信号的线性度而导致的产品一致性差的问题,分析了根据隔离后输出信号来检测原始信号精确度低的问题,提出了一种差分去噪的解决方案。
Operating principle of new type linear optical coupling isolation devices HCNR201 was introduced, influencing factors of poor product consistency caused by the linearity of the input signal and output signal was discussed, detecting original low signal precision problem based on the output signal after isolation was analyzed, differential denoising plan was put forward.
