However, jitter remains a concern; several jitter mechanisms exist for the biphase-mark-encoded signal, the biggest problem being that of bandwidth limitation at any stage of the interface.

然而，抖动依然令人担忧，一些抖动机制双相标记编码信号，最大的问题是存在的带宽限制，在任何界面的阶段。

Because of the limitation of bandwidth, signal must be transmitted in low speed.

由于受传输带宽的限制，要求信号以较低的速率传输。

The conclusion is that the time delay in AO system is the limitation of Bandwidth, and an AO control system should have higher Effective Bandwidth and lower Close Bandwidth.

分析结果认为自适应光学控制系统应当具有较高的有效带宽，较低的闭环带宽，系统中的时间延迟是限制自适应光学控制系统有效带宽的主要因素。
