摘要

PROBLEM TO BE SOLVED: To increase the possibility that a vibration component of a vibration waveform can be completely removed, as compared with the case where a notch filter is applied. A filter for removing a vibration component of a vibration waveform, wherein each of the values of the vibration waveform at arbitrary N (N≧2) time points corresponds to a corresponding weight of N weight coefficients. A filter design device that gives N weighting coefficients to a filter that multiplies a coefficient and calculates an average, wherein each time-series data is a value of a vibration waveform at N time points for each time-series data from the vibration waveform. Acquisition means for acquiring M (M≧1) time-series data including, and for each time-series data of the M time-series data acquired by the acquisition means, vibration at N time points for each time-series data Determining means for determining the N weighting factors so that the condition that the value obtained by multiplying each value of the waveform value by the corresponding weighting factor among the N weighting factors and adding is 0 is determined; Output means for outputting the N weighting factors determined by the means.
