Abstract
In this note we obtain two new sampling formulae for reconstructing signals that are band limited or time limited in the fractional Fourier transform sense. In both cases, we use samples from both the signal and its Hilbert t ransform, but each taken at half the Nyquist rate. (C) 1999 Elsevier Scienc e B.V. All rights reserved.
