摘要
DDS技术具有高分辨率、快速转换、相位连续可控等优点,但也存在因相位截断、幅度亮度与DA转换器的非线性因素等误差造成的杂散。针对DDS信号频谱杂散的原因进行了分析,并对相关抑制方法加以介绍,对各类抑制方法的特点进行了综述。
DDS technology has the advantages of high resolution, fast conversion, phase continuous controllable etc, But there are also exist the error caused by the stray of the phase truncation, amplitude brightness and DA converter nonlinear factors. This paper mainly analysis the DDS signal spectrum stray reason, and introduce the relevant inhibition method, re- view all kinds of inhibition method of characteristics.
