WebThe classical uncertainty principle of quantum mechanics, formulated by Heisenberg, Pauli, Weyl, and Wiener, is an example of such an inequality; and it was applied to signal analysis by Gabor. Weighted and local versions of the classical uncertainty principle inequality are proved in order to provide fine estimation of signal duration.

WebSep 20, 2024 · $\begingroup$ This is the erroneous 'Jacobsen' interpretation of the uncertainty principle. You are simply talking about bin widths with that, nothing more. The Heisenberg/Gabor uncertainty has to do with a pulse width going through the FT. A gaussian is the eigenfunction of the CTFT. Make it wider, and the output is narrower and … Web6.2 The Gabor Uncertainty Principle Gabor proved his uncertainty principle by applying to arbitrary signals the same mathematical apparatus as used in the Heisenberg-Weyl derivation of the uncertainty principle in quantum mechanics. We give our own version of this proof in the chapter appendix (Sec. 6.12.1, p. 144); here our intent is to WebThe uncertainty principle, which states that the time uncertainty and frequency uncertainty cannot be minimized simultaneously, is a bottleneck problem that undermines the faithfulness of sensing and confines the accuracy of analysis. ...
