WebbL' égalité de Parseval dite parfois théorème de Parseval ou relation de Parseval 1 est une formule fondamentale de la théorie des séries de Fourier. On la doit au mathématicien français Marc-Antoine Parseval des Chênes (1755-1836). Elle est également appelée identité de Rayleigh du nom du physicien John William Strutt Rayleigh. WebbIn mathematics, Parseval's theorem usually refers to the result that the Fourier transform is unitary; loosely, that the sum (or integral) of the square of a function is equal to the sum (or integral) of the square of its transform.

Webb8 mars 2024 · Abstract: Parseval’s theorem states that the energy of a signal is preserved by the discrete Fourier transform (DFT). Parseval’s formula shows that there is a nonlinear invariant function for the DFT, so the total energy of a signal can be computed from the signal or its DFT using the same nonlinear function.
