Signal to noise ratios come from the field called signal process and that, if you like, is a quite a technical concept.

信号信噪比来自外地所谓信号的进程，如果你愿意的话，是一个相当的技术概念。

Chaotic signal has the properties of ergodicity, nonperiodicity, continuous broadband power spectra, and noise like etc.

混沌信号具有遍历性、非周期、连续宽带频谱、似噪声的特性。

On the other hand, the dynamic properties of chaos signal such as ergodicity, aperiodic, uncorrelated, broadband and noise-like have been proved to be useful for communication.

同时，混沌信号具有遍历性、非周期、连续宽带频谱、似噪声的特性，特别适合于保密通信。

Have you, like me, abandoned newspaper for Twitter and trusted your social networks to deliver the signal amidst the noise?

FORBES: Where Do You Get Your Science?

Again, you have to deal with signal issues in high-RF noise environments, deal with materials issues acting as RF shields (like in many computer rooms or anything with lots of metal in it), and you have to balance the convenience with the somewhat-increased security risk.
