the paper mainly introduce the applied condition of opto - coupled isolator in isolation of signal, and some noticeable problem.
文中主要介绍了光电耦合器件在信号隔离中的应用情况,以及一些需要注意的问题。
for digital signal of low frequence, using opto - coupled isolator is simpler, but, for digital signal of intermediate or high frequence, the signal will be aberrant.
