The SPLL consists of calculation frequency error, updating loop middle variable, and output control signal.
该锁相环由计算频率误差、更新环路中间变量、输出控制信号组成。

DEVAR current loopsignal isolators reduce problems found in field measurements when signal transmitters or converters encounter both input and output signals that may be grounded.
在信号传感器或信号转换器遇到接地的输入或输出信号时,电流环路信号隔离器减少现场测量难题。
