| Abstract: | As the development of multicarrier communication technology,multi-channel signal generator has become more and more important.Based on the Direct Data Synthesis(DDS) technology,this design uses FPGA to control the AD9910 to implement a kind of multi-channel signal generator.This multi-channel signal generator features high frequency precision,low stray,fast frequency switching,and programmable adjustment of the multi-phase value of the output signal.Measured results show that this method is feasible and effective,and it would be widely applied in the future. |
