摘　　要：调频接收机是通信电子线路课程的重点和难点,具有极强的实践意义。为了培养学生对电路的设计和调试能力,设计了调频接收机综合设计型实验。该文根据实际情况提出了实验项目的内容和要求,设计了系统方案和各部分电路;最后实测和分析了各项技术指标。实验结果表明,实验方案清晰展现了调频接收机的原理以及工作过程,教学效果良好,可为其他高校开设相关课程提供一定借鉴和帮助。Frequency modulation receiver is an important and difficult point in the communication electronic circuit course,which also has strong practical significance. In order to train students＇ design and debugging ability,a comprehensive design experiment for FM receivers was designed. This article proposes the content and requirements of the experimental project according to the actual situation. Then,the system scheme and all parts of the circuit were designed. Finally,the technical indicators are measured and analyzed. The experiment results show that design scheme clearly displayed the principle and working process of FM receiver and favorable teaching effect was obtained. It may be helpful for the other universities to open the correlated curriculum.
