    Abstract
  • This paper introduces the composition, operational principle and performance of DDS, and uses signal theory and method to analyze the effect of phase noise, spurious noise and digital phase truncation error on output wave form and the effect of DAC non-linearity on spectrum purity in detail. Analysis formula and correspondence curve in question are also provided. The conclusion is some instructive to increase the quality of DDS output signal.
