Resumen:
We characterize those frames on a Hilbert space H which can be represented as the image of an orthonormal basis by an oblique projection defined on an extension K of H .We show that all frames with infinite excess and frame bounds 1 =A =B are of this type.This gives a generalization of a result of Han and Larson which only holds for normalized tight frames.
