| Abstract: | The design of digital modulation system is based on the principle of direct digital frequency synthesis(DDS),using MCU(AT89S51) as a control core.The FPGA is taken as a core of data processing.All of the modules are realized in FPGA by means of Verilog HDL programming and found to meet to the design requirements through software simulation and hardware testing. |
