1. A method of constructing a waveform from N sampled data captured at N successive points in time, the method comprising:
applying K data at a time of the N sampled data to each of M delayed replicas of a filter comprising K taps thereby to generate N×M interpolated data, wherein values of the K taps associated with an ith delayed replica of the filter are determined by shifting a function characterizing the filter by a delay between the ith delayed replica of the filter and the (i−1)th delayed replica of the filter, wherein i is an integer varying from 1 to M; and
constructing the waveform using the N sampled data and the N×M interpolated data, wherein K, N and M are integers and wherein K is smaller than N.
