The aim of the present paper is to state an asymptotic property ? of Shannon’s sampling theorem type, based on normalized cardinal sines, and keeping constant the sampling frequency of a not necessarilly band- limited signal. It generalizes in the limit the results stated by Marvasti et al.  and Agud et al. . We show that ? is fulfilled for any constant signal working for every given sampling frequency. Moreover, we conjecture that Gaussian maps of the form e-?t2 ,??R+, hold ?. We support this conjecture by proving the equality given by for the three first coefficients of the power series representation of e-?t2 .
