| Abstract: | The basic principle and the basic structure of DDS technology are analyzed in this paper, which introduces a design method of DDS signal generator based on FPGA. The FPGA chip EP2C35F672C8 is used as the core cell, supplemented by necessary analog circuit. In the Quartus II9.0 platform,synthesis and simulation of the system design is realized. The experiment test shows that the output waveform of the signal generator has the advantages of smooth, high stability and phase continuous, etc. It has a certain engineering practice significance. |
