phase locked loop

基本解釋

This paper gives an analysis of parasitic frequency deviation in the digital phase locked loop, which is one of the important specifications of modern communication systems.
本文分析了數(shù)字鎖相環(huán)路的寄生頻偏，它是現(xiàn)代通訊系統(tǒng)中頻率合成器的重要指標(biāo)之一。
Phase locked loop connected with phase PID control is applied in the middle loop in order to acquire good dynamic process and strong anti disturbance performance as well as high precision.
中環(huán)引入與相位PID控制相結(jié)合的鎖相環(huán)路，保證了系統(tǒng)在達(dá)到高穩(wěn)態(tài)精度的同時(shí)具有好的動(dòng)態(tài)特性和強(qiáng)的抗干擾能力。
Direct synthesizing and phase locked loop are combined to implement the synthesizer. Ultra-light and double shock proof and high efficiency switching power supply are used in the synthesizer.
該合成器采用了直接合成與數(shù)字鎖相相結(jié)合的方法，并采用了超輕型、雙重隔振技術(shù)和高效率開(kāi)關(guān)電源。
