Maybe I'm behind the times. I just learned about stochastic resonance and it kinda blows my mind. You add noise into a system and you get a better signal? Apparently it's a hit with living organisms.
From what I read, it was discovered by some scientists trying to understand how earth's ice ages happen. Makes sense to me.
From the wikipedia article: ..."Stochastic resonance occurs when these conditions combine in such a way that a certain average noise intensity results in maximized information transfer. A time-averaged... output due to signal of interest plus noise will yield an even better measurement of the signal compared to the system's response without noise in terms of SNR."
How weird is that?
