CYCLIC SIGNAL PROCESSING METHOD, CYCLIC SIGNAL CONVERSION METHOD, CYCLIC SIGNAL PROCESSING DEVICE, AND CYCLIC SIGNAL ANALYSIS METHOD

摘要

This invention is not based on a model of the spectrum , and also capable of reducing the influence of the cycle periodicity signal processing method , periodic signal conversion method , and the period related to the signal processor . The basic period in the time direction of the signal having a periodicity n (n is an integer of 2 or more) each arranged to keep the center of the dividing position for dividing a time window of 1 min , and take- up range is another plurality of portions , each time window calculating a power spectrum for the plurality of portions drawn by , and adding the calculated power spectrum at the same rate . ;
