摘要
DDS具有稳定度高、转换时间短,且分辨率较高等优点,本文提出了基于FPGA芯片设计DDS系统的方案。该方案利用Altera公司的QuartusⅡ开发软件,结合DDS的结构和原理,给出系统设计方法,并推导得到参考频率与输出频率间的关系。
One design scheme of DDS system base on FPGA is introduced for the merits of fast frequency,conversion time and high resolution.This paper proposed DDS system based on FPGA chip design program.With the Altera's Quartus Ⅱ development software,We derived reference frequency and output frequency relationships.
