Frequency modulation transmitter is an important and difficult point in the communication electronic circuit course, which also has strong practical significance, frequency modulation （FM） transmitter integrative design experiment was designed ac- cording to train students＇ design and debugging ability. This article has designed the FM transmitter integrated design experiment. Proposed the design of the project content and requirements, through the circuit design and simulation verify the fesaibility of the cir- cuit, and the measured data were analyzed. The experiment results show that design scheme clearly displayed the principle and work- ing process of the FM transmitter. The teaching effect is good, which can provide some reference and help for the colleges to set up re- lated courses.
