摘　　要：锁相环及其应用电路是"通信电子电路"课程教学中的重点内容。本文设计了基于Multisim的锁相环应用仿真电路,并将其引入课堂教学和课后实验。文中首先给出了锁相环的仿真模型,然后构建了由其构成的锁相环调频、鉴频和接收仿真电路,并给出了仿真波形。实践证明,采用这种方式可以帮助学生对相关内容的理解,并为今后进行系统设计工作打下良好的基础。The phase-locked loop and its application circuit are key content in the teaching of Communication Electronic Circuit. This article designs some PLL application circuit based on Multisim and introduces it into teaching in class and experiment after class. First, it gives the PLL simulation model. Then it gives the simulation model of frequency modulator, frequency detector and receiver circuit based on Multisim. Finally , it gives the simulation profile . The practice proved that , this method can help the students to understand correlation content, and build good foundation for further system design work.
