Abstract
There is described a pulse analyzer (1) for sampling a pulse or a repetitive stream of pulses. The pulse analyzer multiplies a pulse by a set of basis functions (c1, c2) to generate a plurality of multiplied pulse functions, and a synthesizer (9a, 9b, 13) combines the multiplied pulse functions to generate a pulse sample. In particular, the synthesizer 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 synthesizer corresponds to a pulse sample for a sample time interval shorter than the integration interval.

A pulse analyser for sampling a pulse or a repetitive stream of pulses, the pulse analyser comprising:
- a multiplier that multiplies a pulse by a set of basis functions to generate a plurality of multiplied pulse functions;
- and
- a synthesiser configured to combine the multiplied pulse functions by performing at least one integrating operation over an integration interval substantially corresponding to the duration of the pulse and at least one adding operation to generate a pulse sample,
- where the pulse sample has a sample time interval shorter than the integration interval.
A method of analysing a pulse, the method comprising:
- applying an analysis function to the pulse by deriving a sample value for each of plural time instants within the duration of the pulse, each sample value being derived by combining the pulse with each of a plurality of spectral components of a version of the analysis function for the respective time instant;
- and
- deriving a combination of the results by performing an integrating operation over an integration interval substantially corresponding to the duration of the pulse and at least one adding operation.
