| Abstract: | Direct digital synthesizer technology is widely applied in digital communication system. Based on studying the basic theory of direct digital synthesizer technology, this paper makes model design of DDS with DSP Builder of FPGA and applies DDS to digital modulation system. The correctness and feasibility of DDS will be proved through simulation analysis, the configuration downloading process to FPGA device was completed through Quartus II. |
