随着科学技术水平的发展,我国电子通信在随着市场需求的不断转变的过程中也在发生相应变革。锁相环技术被广泛地运用到通信系统中去,主要通过负反馈系统来实现本地参考信号与接收信号的相位统一,信号输入主要通过锁相环的鉴相器、环路滤波器和压控震荡器三个主要器件输出信号后,完成其工作流程。基于此,对锁相环技术的发展进行研究,并对其运用情况进行介绍。
With the development of the science and technology level, the electronic communication in our country is correspondingly changing in the process of continuous changing with the market demand. Phase-locked loop technology is widely used in communication systems, mainly through the negative feedback system to achieve the local reference signal and the phase of the received signal unity, the signal input through the phase-locked loop phase detector, loop filter and voltage-controlled Oscillator three main components output signal, complete its workflow. Based on this, the development of PLL technology is studied, and its application is introduced.
