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.
鎖相環路是一種能實現相位自動鎖定的控制系統，主要用於頻率郃成及跟蹤解調系統。
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.
