Abstract : The goal of this paper is characterize finite-length signals that have a low-rank short-time Fourier transform. By using the connection with Hankel matrices, we give a comprehensive answer in case of maximal overlap, where the class of signals includes products of complex exponentials and polynomials. In the general case, other exotic examples may appear.
