As we know, spuriousnoise of a DDS resulted from phase truncation degrades its spectral characteristics.
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。

Signal filter: signal filters can be useful in a number of circumstances, such as when spuriousnoise is inadvertently added to the signal as it travels through the switch.
信号滤波：在许多的环境下，信号滤波是非常有用的，例如当信号通过开关时会加入寄生噪声时。

In addition to high power, the amplifiers also provide improved performance due to very low phase noise and spurious.
