Suboscillations with arbitrary shape
arXiv:1705.02977 · doi:10.1088/1751-8121/aa7c67
Abstract
We report a method for constructing bandpass functions that approximate a given analytic function with arbitrary accuracy over a finite interval. A corollary is that bandpass functions can be obtained that oscillate arbitrarily slower than their minimum frequency component, a counter-intuitive phenomenon known as suboscillations.
