| Abstract: | The article introduces the principle, the circuit diagram and the optimization method of realization DDS based on FPGA. The importance of how to realize DDS through FPGA is introduced,and some VHDL source procedure is given. The chip adopts the ACEX series EP1K30TC - 144 that is made in the Altera. Above all, this DDS system possesses some characteristics including high performance,high proportion between price and performance and simple circuit diagram,and so on. It can be embedded into other system easily without special DDS chip. |
