Abstract
A method for calculating the coefficients of the Gabor expansion in th e case of oversampling is presented. The method is based on the concep t of frames and utilizes the Zak transform. As such, the Zak transform highlights the meaning and importance of frames in the context of ove rsampling, and other aspects of signal representation by means of nono rthogonal bases.
