In addition, the stop-band rejection can be further increased by using elliptic filter function which has limited frequency transmission zeros.

另外，在函数类型上使用椭圆函数型，使带外出现有限频率传输零点，进一步提高了带外抑制能力。

The function of a loop filter is to filter high-frequency signal out of the output voltage from PFD and CP, thus the output signal from VCO will be purified.

环路滤波器的作用就是滤除从PFD&CP出来的电压中的高频成分，从而纯化VCO的输出信号。
