In frequency synthesis by phase lock, the loop gain will vary by the same amount due to this effect, which generally im - pedes optimization of loop performance.
在锁相频率合成器中，由于压控灵敏度的变化，环路增益也将产生同样大小的变化，这就妨碍了环路特性的最佳化。
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。
