This allows ... WebWhat engineers like to call a white noise process is a hypothetical beast that is never observed directly in any physical system, but which can be used to account for the fact that the output of a linear time-invariant system whose input is thermal noise is well-modeled by a wide-sense-stationary Gaussian process whose power spectral density is ...
WebOct 23, 2013 · There is some place where it "really is", but that's not intrinsic to A. In this example, you can think of wind as a kind of "process noise". (Not a great example, since it's not white noise, but work with me here.) The wind is a 3-dimensional process noise affecting the cannonball's velocity; it does not directly affect the cannonball's position. WebExamples of Stationary Processes 1) Strong Sense White Noise: A process ǫt is strong sense white noise if ǫt is iid with mean 0 and finite variance σ2. 2) Weak Sense (or second order or wide sense) White Noise: ǫt is second order sta-tionary with E(ǫt) = 0 and Cov(ǫt,ǫs) = σ2 s = t 0 s 6= t In this course: ǫt denotes white noise; σ2 de-
