Abstract:
The classical Shannon sampling theorem has many extentions [A Tutorial in Theory and Applications, C. K. Chui, ed., Academic Press, 1992, pp. 51-70], one of which is to functions of polynomial growth. In this paper, we shall prove the following theorem: Let F(ω) be a distribution with compact support on [-π, π] and f(t) be the Fourier transform. Then f(t) = ∑n f(n)sin π(t - n)/π(t - n) holds in the sense of (C, α) summation under a very mild condition. The above result improves the theorems in both [SIAM J. Math. Anal., 19 (1988), pp. 1198-1203] and [Generalized Functions, Convergence Structures, and Their Applications, B. Stankovic et al., eds., Plenum Press, 1988, pp. 349-357] given by G. G. Walter.
