We introduce a new concept of variable bandwidth that is based on the truncation of Wilson expansions. For this model we derive both (nonuniform) sampling theorems, the complete reconstruction of a function from its samples, and necessary density conditions for sampling.
Joint work with Karlheinz Gröchenig (University of Vienna).
