由于杂散性能较差是DDS应用受限的主要原因，本文从理论和实际应用两个方面着重分析了实际参数DDS的输出频谱特性。
The bad spurious performance is the major problem that restricts the applications of DDS, so the theoretical and practical analysis attaches importance to the spectrum performance of DDS.
由于相位舍位会导致直接数字频率合成器(DDS)的输出产生杂散，使其频谱特性恶化。
As we know, spurious noise of a DDS resulted from phase truncation degrades its spectral characteristics.
