The main problems of signal integrity of high-speed digital system include reflection, crosstalk, delay, ringing, simultaneous switch noise, etc.

高速数字系统的信号完整性问题主要为反射、串扰、延迟、振铃和同步开关噪声等。

The results demonstrate the cross correlation filter not only can suppress random noise in GPR signal but also confirm exactly the onset of reflection wave.

结果表明：应用该文所介绍的处理方法不但能有效压制探地雷达信号中的随机干扰而且能精确确定反射波的起跳点。

The holographic volume gratings and reflection holograms having high diffraction efficiencies and signal noise ratio are also fabricated in experiment.

实验中制作出了高衍射效率和信噪比的体积全息光栅和反射全息图。

Some of them now qualify for the Order of Celebrityhood. (Not much more can be said of CEOs who pass off their ghost-written banalities in bookstores everywhere.) Is this noise really contributing to a base of public knowledge and reflection that makes for better and richer societies?
