摘要
讨论了直接数字频率合成器(DDS)的工作原理,并根据正弦波的特点对ROM进行优化.优化的ROM在Flex10k10的FPGA芯片上实现,对实验结果进行比较和分析发展,该方案可以有效地改进DDS的精度.
This paper has discussed the principle of Direct Digital Frequency Synthesizer （DDS） and researched on the method of optimizing ROM by the characteristics of sine wave. The method has been implemented in FPGA chip （type Flex10k10）,and the experimental results has been compared and analyzed.
