Design and Practice of Frequency Modulation Receiver Experimental Project

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.
