The present invention is embodied in a system for the analysis and design of direct digital synthesizers including a windowing engine, and a method that enables the analysis of DDS output spectra in the presence of phase truncation and arbitrary approximations and errors in the implementation of the sine/cosine mapping function (SCMF) without the need to approximate the DDS characteristics.
