摘要 本文通过分析直接数字频率合成器的工作过程,利用相位截断误差与频率控制截断字的关系,提出了一种抑制杂散的途径。 The processing of Direct Digital Frequency Synthesizer (DDS) is analyzed and the relation between phase truncation error and frequency control truncation word is derived.A method of repressing spur caused by phase truncation error is pressented.
