Linear Version of Parseval’s Theorem
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 <italic>invariant</italic> function for the DFT, so the total energy of a signal can be computed from the s...
