WebOct 28, 2012 · It is shown in this paper that minimal bound of high frequency spectrum is reached when a gaussian switching pattern is used. This result is proved by using the Heisenberg-Gabor uncertainty principle (widely known by physicists in quantum mechanics). Published in: IECON 2012 - 38th Annual Conference on IEEE Industrial … Web2 days ago · For a study, researchers manipulated exogenous temporal attention and the uncertainty of stimulus timing separately and assessed visual performance at attended and unattended moments with different levels of temporal uncertainty. Two Gabor patches were presented consecutively with a variable stimulus onset time during each trial.
WebI think Gabor's uncertainty applies strictly to the unaliased signal we can measure. Then, as you say, another problem is that we have to take time chunks to measure frequency … WebGabor's proof of the uncertainty principle Although it is easy to verify the uncertainty principle in many special cases, it is not easy to deduce it. The difficulty begins from finding a definition of the width of a function that leads to a tractable analysis. One possible definition uses a second moment; that is, is defined by (2)
