phase-lock system

基本解釋

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(huán)路是一種能實(shí)現(xiàn)相位自動(dòng)鎖定的控制系統(tǒng)，主要用於頻率郃成及跟蹤解調(diào)系統(tǒng)。
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.
