| Abstract: |
| The realization of direct digital synthesizer (DDS) by FPGA based on the principle of fraction division is introduced.It's principle,structure and realization method are also given.Then the linear function relationship between output frequency and reference frequency is deduced.The DDS is high frequency stability,accuracy and resolution that can easy to preset and display the output frequency by single chip computer easily. |
| Key words: FPGA direct digital synthesizer single chip computer |
