The real question is what veterans of cyberspace call the "signal to noise ratio."
At some point, the noise ratio is so high that you can do nothing but answer your telephone.
In radio operator lingo, you look for a strong signal to noise ratio.
For a decade, the web kept delivering an ever better signal to noise ratio to me.
The signal to noise ratio of the point sources increases with stronger selection.
If we didn't do it, the signal to noise ratio would change dramatically for the worse.
This feature could be used to enhance signal to noise ratio in image systems.
The resulting effect of enhancing signal to noise ratio on the channel is called process gain.
Low level signals will give a lower (and almost certainly inadequate) signal to noise ratio.
So, the easiest way to improve the signal to noise ratio is to crank up the power.
