DDS应用的频率规划及相位抖动分析

DDS frequency planning and analysis phase jitter

介绍了DDS原理,以及DDS应用的频率规划的意义和主要内容。并以相位抖动为出发点,详细分析了其相位误差。运用傅里叶级数,研究DDS在有相位抖动时,D/A输出端的频谱特征,给出DDS输出频谱杂散散布顺序。

Introduced the DDS principle, and the significance of DDS frequency planning and the main content. In phase jitter as a starting point,a detailed analysis of the phase error. The use of Fourier series,the output spectrum of research DDS law.
