Electronic Noise: When can it be your friend?

Because electrical signals are used everywhere to transmit information, ever-present electronic noise can obscure or corrupt the flow of information. This fact alone creates the need to be able to quantify noise. But the ability to quantify noise brings with it some positive outcomes, too. Pure-noise experiments can give values for fundamental constants (such as Boltzmann's constant kB or the fundamental electrical charge e), and can also make possible first-principles noise thermometry. Finally, through the use of Fourier methods, electronic noise can be used as a 'spectral resource', as valuable in its way as white light is in optics.
