| Abstract: | The development in spurious reduction technology of DDS in the recent years is introduced.The principle and application of phase-moving,admixture-frequency syntheses,inside-phase are studied.And based on the admixture-frequency syntheses,a kind of frequency synthesis is designed,which has better function-higer purity on frequency spectrum and is able to rapid spreads spectrum. |
