But after exposure to loud noises, these cells can start behaving aberrantly, messing up their timing so they begin to synchronize their signals and fire without a noise to tune out, which results in a perception of sound where none exists.

They begin to bleed together and resemble little more than signal noise, but she breaks out of morass deftly in The Post.

The noise cancellation system does a nice job of filtering out excess racket from the mechanical parts and systems, and we enjoyed the brief moments of pure silence when the car came to a stop and both engines would shut down, saving fuel and patiently waiting for us to lift our foot off the brake pedal as a signal to get things moving again.

Ironically, most of his takeaways are things that weren't unknown to anyone paying attention a year ago, including the value of an email list; the importance of an author's platform; the increasingly out - of - whack signal: noise ratio in the market; print as premium product; the power of free promotions combined with targeted marketing; and, perhaps the most obvious, ebooks have a long way to go before they replace print.

It's the reason why people hire and pay the wages for marketers and promoters — getting enough signal attached to your book to boost it out of the noise and into the public eye.

However, signals on the lower time frames are naturally less reliable than signals on the daily chart because the daily chart works to «smooth» out the noise and randomness that can occur on time frames below it, thus showing you a more accurate picture of the market.

Think of the daily chart as a sort of natural «filter» for bad trade entries, since it filters out the noise and irrelevancy of the lower time frame price movement and as a result, the signals on the daily chart are more reliable.

I remember when I first got started day - trading, there was so many false signals and noise... most of the time I would get stopped out almost as soon as I entered a position.

The methods one develops for this should be able to handle a reasonable amount of non-climatic noise and still pull out the correct signal.

These archives can be corrupted with non-climatic noise, but by putting a lot of them together we hope to be able to figure out the common signal in time and space since the non-climatic noise will not be correlated across all proxies.

What I was reminded of though is something along the lines of the hypothesis of a very weak signal / stochastic - resonance idea, where «noise» and a very weak «signal» could combine (similar to some of the D - O hypotheses out there).

If there is any Climate Sensitivity to CO2, to date we have been unable to eek out the signal to CO2 induced warming from the noise of natural variation notwithstanding the use of our best and most sophisticated measuring devices and the inherent shortcomings of our measurement systems and error bounds.

It is therefore a gross over simplification to say weather (ie turbulence) = noise can be averaged out to pick up some kind of imaginary background bulk signal.

Meanwhile it does not answer the main point of my last post, which is that that most climatologists view this aspect of the earth's environment as «weather» (or statistical noise) and that if you measure temperatures for long enough periods of time (30 + years) the effect of clouds, rain and water vapour average out and a temperature trend signal will become apparent.

The noise that many want to cancel out or dismiss or claim that it all adds up to zero is a cacophony of interfering and amplifying signals from the elsewhere that are poorly understood at best.

Th only possibilities consistent with the theory are: (1) if you don't see warming in a particular metric, it is the result of the lack of good metrics or because it is out there somewhere or, (2) if you don't see warming and you think the metrics valid, then what you are looking at is an insignificant trend — just noise amidst the signal.

In contrast, in electronics, dealing with one - off events, noise is something that has a value that can not be diminished, and the key is not how to average it out, but out to make meaning of the signal: how strong is the signal to the noise.

In the end, the antics of the ocean and WV, which may indeed have the sun as the conductor, far outweigh that of co2 though an underlying signal may be there, which given the way temperatures bounce up and down in response to the enso, may be no greater than noise Peace out

Under such circumstances, the noise will cancel out in a linear combination of proxies (reconstruction) and a «signal» will emerge.
