Design of a fast-acquisition phase-locked loop for frequency control systems

Dianzi Jishu Yingyong
Phase-locked loop (PLL) is a negative feedback control system that can achieve phase synchronization of two signals. Its filtering effect can make its passband narrow, and its output frequency automatically track the input frequency.
