Poles and zeros of the transferfunction play an decisive role for filter performance.
滤波网络传输函数的零点、极点位置对滤波性能起着决定作用。

It is proposed that LCR output filter can decrease the peak value of the gain of voltage transferfunction as well as the high frequency burr contained in the source current.
The systems transferfunction is analyzed, especially the one of the filter which is connected between VFD and the phase detector, and it should be established on the group delay concept.
