| Abstract: |
| The application of direct digital frequency synthesis(DDS) technology and anologue technology of Phase Lock loop(PLL) is introduced,which is a new kind of application in frequency synthesis.It has good characteristics,such as small size,high frequency resolution,fast switch time and low phase noise.DDS is very perfect in application if a great deal of spur is suppressed. |
