Abstract
A proven basic technique for the digital generation of two sine waves having a known and adjustable phase difference has been used to produce a commercial phase-angle standard. While the final performance for this instrument meets or exceeds those previously reported for a unit built by the National Bureau of Standards, a number of different circuit techniques have been used to achieve greater phase resolution, circuit simplifications, easier mechanisms for detecting possible circuit problems, and significant cost reductions.Keywords
