Due to the frequency pulling of FLL, the passband of the filter in PLL can be made very narrow to suppress the noise, and the PLL can lock carrier's phase with high accuracy.
由于有锁频环的频率牵引，锁相环路滤波器可以设计得很窄，具有很好的抑噪性能，满足精确跟踪载波相位的要求。
With the click of a few keys, I can send each of them a message, pulling them into my life in Numbers and with a frequency that was unthinkable twenty years ago.
点击几个键，我可以给每人发送消息，从数量上把他们拉进我的生活，这种频率在二十年前是不可想象的。
The pulling frequecncy needs to be high to ensure high data accuracy, but high pulling frequency may induce redundant checks leading to high network traffic.
这种拉取 方式的频率要足够高才能保证很高的数据精确度，但高频率可能会导致多余的检查，从而导致较高的网络流量。
Low pulling frequency, on the other hand, may lead to missed updates.
而另一方面，低频率则会导致错过更新的数据。
Low pulling frequency, on the other hand, may lead to missed updates.
