Webblim ϵ → 0 1 2 ϵ ∫ f 1 f 2 s ( f + ϵ) − s ( u − ϵ) 2 d u. This succeeds in defining S almost everywhere. Now even if S is not differentiable, it does define a distribution, and its derivative in the sense of a distribution can be defined as the power spectral density. But since S can have jump discontinuities, its derivative can ... WebbThe ESD of an energy signal for any frequency can be interpreted as the energy per unit bandwidth, which is affected by frequency components of the signal around that … WebbWelcome to the largest collection of MCQs on the Internet. ...
