There is described a pulse analyser (1) for sampling a pulse or a repetitive stream of pulses. The pulse analyser multiplies a pulse by a set of basis functions (c1, c2) to generate a plurality of multiplied pulse functions, and a synthesiser (9a, 9b, 13) combines the multiplied pulse functions to generate a pulse sample. In particular, the synthesiser performs at least one integrating operation over an integration interval substantially corresponding to the duration of the pulse and at least one adding operation. The basis functions are such that the output of the synthesiser corresponds to a pulse sample for a sample time interval shorter than the integration interval.
