A technique for reducing the spurious signal content in digital sinusoid synthesis. Spur reduction is accomplished through dithering both amplitude and phase values prior to word-length reduction. The analytical approach developed for analog quantization is used to produce new bounds on spur performance...http://www.google.fr/patents/US5459680?utm_source=gb-gplus-shareBrevet US5459680 - Method and apparatus for spur-reduced digital sinusoid synthesis
