Fast sinc interpolation of digitized signals using the Hilbert transform.
Sinc interpolation is a useful method for improving digital waveforms measured by A/D converters. This algorithm reconstructs the intermediate points between sampled data. I describe here a fast method for computing the sinc interpolation by the use of the Hilbert transform.
