On the reconstruction of bandlimited signals from sampled values

Creator:: Dastrange, Nassar
Abstract:: The sampling theorem states that any frequency bandlimited signal can be exactly reconstructed from its sampled values. Different forms of this theorem have been reviewed since 1841 up to the present time. Kramer's generalized sampling theorem has been extended to two dimensions, and the form for higher dimensions can be...
