这些延迟会造成“梳状滤波效应”(相位的抵消和叠加)，这会改变拾取信号的音质。

This delay can cause "comb filtering" (phase cancellation and addition), which alters the miked signal's tone.

他指出，由于布拉格衍射效应，在同样具有螺旋结构的胆甾相液晶中也观察到了类似的光子自旋滤波。

He points out that a similar spin-filtering of photons due to Bragg diffraction has been seen in cholesteric liquid crystals, which also have a helical structure.

提出的辅助判决均衡器在用于滤波多音调制系统时，可克服判决反馈均衡器在多径信道下的地板效应。

For the FMT system, a decision-aided equalizer could overcome the floor effect of the decision feedback equalizer which is caused by the multi-path channel.
