The Analysis and Simulation of Low-Spurious DDS
Tan Ya-jun · Journal of Guizhou University · 2009
The method of time-domain waveform was adopted to analyze these influence generated by the phase truncation in the output spectrum and the distributed pattern of their error frequency spectrum was provided.With the assistance of computer simulation Matlab,the conclusion was tested.The phase-dithering method was employed to suppress DDS phase truncation,which ultimately leads to improvements in the purpose of DDS output spectrum features.The method has done a rigorous analysis and use simulation tools to verify the theoretical analysis results.
