| Abstract: | Combining the two synthesis techniques, DDS and PLL, the authors succeed in designing a kind of frequency synthesizer that has lower spurious signals and rapid spreads spectrum. The output and the frequency spectrum of the new synthesizer show that it is superior to both the traditional PLL frequency synthesizer and the pure DDS frequency synthesizer. |
