Sampling approximation of continuous functions with multidimensional domain


After evaluating Shannon’s sampling theorem for functions of several variables, the aliasing error is estimated in dependence upon smoothness conditions. As a main tool the concept of multidimensional convolution integrals is introduced, in particular those of de La Valke Poussin, which are also helpful in constructing generalized sampling series having… (More)
