Kapanadze and other FE discussion

stochastic resonance is interesting ...

they say that a normal (casual) :)varicap transforms the thermal noise voltage into a potential difference across the terminals. It is too small to measure with a microvoltmeter, even with an input resistance of 1MΩ.It accumulates on the parallel condenser for a minute, then connects to the device. I tried, I did not succeed.  Why?

think  about white noise
1. did you have white noise?
2. what in your opinion is the difference between thermal noise and white noise?

Stochastic Resonance.  A stochastic resonance is a phenomenon in which a nonlinear
system is subjected to a periodic modulated signal so weak as to be normally undetectable,
but it becomes detectable due to resonance between the weak deterministic signal and stochastic noise.
The earliest definition of stochastic resonance was the maximum of the output signal strength as a function of noise (Bulsara and Gammaitoni 1996).

this one is not about resonance  but is easy  enough  for understanding

this video is very good.

@tysB3,

when I saw your coil-arrangement I rememered the subject unilateral-induction by [size=0pt]Eugene M. Efimov[/size][/color]
