phase-lock system

基本解释

The phase- locked loop is one kind of control system which is able to achieve phase automatic lock, to compose frequency and to trace demodulation system.
锁相环路是一种能实现相位自动锁定的控制系统，主要用于频率合成及跟踪解调系统。
The real-time and parallel processing ability of the system is investigated. The phase-lock azimuth transform and infrared registration recognition are implemented in the system.
研究了数字锁相实施玫瑰线扫描同步采集方位转换和红外多帧配准图像模糊分割识别系统实现。
The system has picked up unbalanced (fundamental frequency) signal amplitude and phase accurately by adopting the fourth order band-pass following filter controlled by phase-lock loop and FFT.
系统设计中采用锁相环控制的四阶带通跟踪滤波、FFT实现了不平衡（基频）信号幅值和相位的精确提取。
