Irregular sampling for hyperbolic secant type functions

Anton Baranov, Yurii Belov

We study Gabor frames in the case when the window function is of hyperbolic secant type, i.e., $g (x) = (e^{a x} + e^{- b x})^{- 1}$ , $Re a, Re b > 0$ . A criterion for half-ir…

Frame set for shifted sinc-function

Yurii Belov, Andrei V. Semenov

We prove that frame set $F_{g}$ for imaginary shift of sinc-function $g (t) = \frac{sin π b ( t - i w )}{t - i w}, b, w \in R ∖ {0}$ can be described as $\mathcal{…
