The article introduced the basic structure and the realization principle of direct digital frequency synthesizer (DDS), and analyzed main properties of DDS system, compared the different ways to achieve frequency synthesis to determine the design scheme in this paper. In addition to the realization of general waveform, the output of the system can realize any hand-painted waveform, improve the shortcomings of the current function generator, and also has the advantages of low cost, low power consumption, short development cycle, flexible design, has the very good practical value and broad application prospect.
