A novel truncation spurs free structure of direct digital synthesizer

Purpose - Spurious frequencies (spurs) resulting from phase truncation are one of the main signal integrity issues for direct digital synthesizers (DDS). The standard approach in DDS design consists of truncating the phase word output from the phase accumulator, in order to minimize the size of the...
