Correlation function derivation

WebFrom the expression of the Energy used in the derivation of Parseval’s theorem (equation 7-9) we can see that energy is given by the zero lag autocorrelation φ xx(0)=x(τ) 2 −∞ ∞ ∫dτ=X(f)2df −∞ ∞ ∫=E (8-11) Normalized Cross-Correlation In seismology we often use correlation to search for similar signals that are repeated in ... WebNov 23, 2024 · From this I can create the two dimensional random process V ( x, y) (using the Wiener–Khinchin theorem and phase-randomization). So far so good. What I want in addition, is that the x -Integral of the autocorrelation function of the y -derivative is zero. So: ∫ − ∞ ∞ C F ( x) d x = 0. F ( x, y) = ∂ V ( x, y) ∂ y.
