Abstract
An object of the invention is to shorten a measurement time while preventing deterioration in resolution during frequency analysis and preventing a reduction in measurement range. A pulsimeter (1) includes a pulse data acquisition unit (100), a replication unit (16), and a frequency analysis unit (17). The replication unit (16) generates, when the number of pieces of acquired sampling data for a pulse rate calculation reaches n, m pieces of sampling data using the n pieces of sampling data and data obtained by replicating n-th sampling data. The frequency analysis unit (17) performs a frequency analysis on the m pieces of sampling data.
