FSK is a kind of modulation mode which is used in lots of wireless communication system.It has the advantage of strong anti-jamming.Using of the Direct Digital Frequency Synthesizer(DDS) technology to realize the FSK modulation has the advantages of high-speed modulation rate response,expedient control,and simple structure.Based on the AD9954,the prototype is designed and tested.The test result proves that the method is feasible,and it will have extensively application.
