WebbIn operator theory, a bounded operator T: X → Y between normed vector spaces X and Y is said to be a contraction if its operator norm T ≤ 1. This notion is a special case of the concept of a contraction mapping, but every bounded operator becomes a contraction after suitable scaling.The analysis of contractions provides insight into the structure of … Webb22 feb. 2024 · When you prove parseval's theorem and plug in ffts, there is a sum over the product of a couple of complex exponentials, and that sum is zero except for one instance where the product of the exponentials is 1.

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.
