WebbEm matemática, Teorema de Parseval comumente se refere ao resultado que a transformada de Fourier é operador unitário; vagamente, que a soma (ou integral) do quadrado de uma função é igual a soma (ou integral) do quadrado de sua transformada. Isto se origina de um teorema de 1799 sobre séries matemáticas por Marc-Antoine … WebbDas Parsevalsche Theorem beschreibt demnach die Berechnung der Energie im Zeit- und Frequenzbereich. Der Ausdruck X (ω) 2 wird deshalb auch als Energiedichte …
