In order to realize the direct digital frequency synthesis(DDS)signal generation,In this paper,based on direct digital frequency synthesizer of the work principles,basic structures,features analysis and the output spectrum,using the MATLAB language programming,combining graphic user interface(GUI),adjusting the parameters k(1≤k≤100),can produce time domain and frequency domain waveforms of 1 Hz～100 Hz arbitrary frequency and generate the direct digital frequency synthesis signal,to meet the design requirement.
