CYCLIC SIGNAL PROCESSING METHOD, CYCLIC SIGNAL CONVERSION METHOD, CYCLIC SIGNAL PROCESSING DEVICE, AND CYCLIC SIGNAL ANALYSIS METHOD |
摘要 |
The invention relates to a periodic signal processing method, a periodic signal conversion method, and a periodic signal processing device capable of reducing the influence of periodicity without using a spectral model. Time windows are arranged such that a center of each of the time windows is at a division position which divides a fundamental frequency in a temporal direction into fractions 1/n (where n is an integer equal to or larger than 2) so as to extract a plurality of portions of different ranges from a signal having periodicity. A power spectrum for the plurality of portions extracted by the respective time windows is calculated, and the calculated power spectrum is added with a same ratio. |
