摘要
在详细分析锁相环基本原理的基础上,建立了锁相环的数学模型,通过PSpice仿真软件对锁相环的鉴相、幅频特性以及压控等各部分性能进行仿真分析,以验证锁相环设计的合理性.
Through detailed analysis on fundamental principle of phase-locked loop, the mathematical model of phase-locked loop was built. Based on PSpice simulation software, the characteristics including phase discrimination, amplitude-frequency characteristics and voltage control were analyzed, and the rationality of phase-locked loop design was confirmed.
