Abstract: This thesis describes a technique for the digital reconstruction of one and two dimensional signals from a series of undersampled versions.To do the necessary alignment of the signals, a novel technique of shift estimation is developed, based on the phase of the Fourier components.The effects of windowing, when finite length signals are processed, are also studied.The reconstruction technique-is based on the frequency domain, and requires that the signal is bandlimited and the total number
