Smile Stochastis Resonance for Electronic LRL's

Maybe this is what the Stimulator Circuit in Mineoro and Other LRL'S is actually doing?

Stochastic resonance (SR) is a phenomenon where a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies. The frequencies in the white noise corresponding to the original signal's frequencies will resonate with each other, amplifying the original signal while not amplifying the rest of the white noise (thereby increasing the signal-to-noise ratio which makes the original signal more prominent). Further, the added white noise can be enough to be detectable by the sensor, which can then filter it out to effectively detect the original, previously undetectable signal.

Hi Astro Detect,
again, a nice subject from you.
If finally this hypothesis has something to do with mineoro,
then probably it's: sine (stimulator) + noise ("signal" from metals)

Being old signal processing guru it does work. Also many other techniques for enhancing signal detectibility.

Maybe instead of the Mineoro Stimulator build a white noise stimulator instead and test it in the DCH85 or other circuit??

Hi Goldfinder, so if it works why don't we concentrate on this to build a decent circuit and see if we can locate buried metals from a distance?

So we must transmit white noise (as stimulator) and receive and filter it.
Maybe will be a good project for the winter

Default Better methods to detect a signal in noise

Have at it. I have better things to do with my time.

White noise has certain characteristics. Signals are have different. Use some kind of pattern detector and scan the received signal for a signal different from white noise. You need some fancy signal processing software to do this. (hint)

Laugh all you want Astrod - digital signal processing is well known to those who have the background.

Good idea Geo you are very good with electronics so let's try this and see the results!!!
