Tags Noise Variance White noise In summary, the conversation discusses the concept of white noise and its infinite power, despite having a finite variance. The definition of white noise is that it has a constant power spectral density (PSD) over all frequencies, leading to an infinite power whe...
noise density of a current I = e N is i_N = sqrt(2 e I) = e * sqrt(2N) rather than e * sqrt(N) The reason is that a 1-second boxcar has a bandwidth of 0.5 Hz on account of the negative frequencies being chopped off, so the sqrt(N) noise is compressed into half the ban...
2024 Still, the researchers identified significant variance among the species: Black cherry, red maple and white ash tended to experience peak coloration earlier, while oaks and sugar maples blazed later. Benjamin Cassidy, Smithsonian Magazine, 11 Oct. 2024 So high variance means some of these ...
"The attached example shows that the Allan variance of white noise is equal to the variance of the individual points divided by the length of the averaging interval. This is the familiar decrease in RMS noise with the square root of the averaging time." And here is the code itself: //All...

We introduce the notion of a functional variance process to quantify variation in functional data. The functional data are modeled as samples of smooth random trajectories observed under additive noise. The noise is assumed to be composed of white noise and a smooth random process—the functional ...
