Generalized Poisson Summation Formulas for Continuous Functions of Polynomial Growth

Abstract: The Poisson summation formula (PSF) describes the equivalence between the sampling of an analog signal and the periodization of its frequency spectrum. In engineering textbooks, the PSF is usually stated formally without explicit conditions on the signal for the formula to hold. By contrast, in the mathematics literature, the PSF is commonly stated and proven in the pointwise sense for various types of L 1 signals. This L 1 assumption is, however, too restrictive for many signal-processing tasks that demand th… Show more

“…It is clear that otherwise the corresponding generalized function already belongs to one of these two spaces. This validity statement is furthermore obtained in good agreement with many other publications devoted to this topic, including [4,[55][56][57][58][59], except for the fact that, in this as well as in our previous studies, we generally do not move away from the overall principle that all functions must be infinitely differentiable. It is the default, tacit assumption in distribution theory.…”

“…It is a given fact for all functions in generalized function spaces. Also recall that O M is the space of multiplication operators in S and O C is the space of convolution operators in S according to Laurent Schwartz' theory of distributions [14,16,[24][25][26][27][29][30][31].…”
