Original Abstract Submitted
a signal processing method includes a time waveform acquisition step of acquiring, from an i-th sensor, an i-th time waveform related to an i-th physical quantity generated by an external force, a velocity, or a displacement having at least a periodic variation acting on an object for each integer i of 1 or more and n or less with n being a predetermined integer of 1 or more, a frequency spectrum generation step of generating an i-th frequency spectrum for each integer i based on the i-th time waveform, and a first state index calculation step of calculating, for each integer i, a difference between a phase of a first signal component corresponding to a first peak included in a first frequency spectrum and a phase of a second signal component that corresponds to a second peak included in the i-th frequency spectrum and has a frequency that is a rational multiple of a frequency of the first signal component as an index indicating a state of the object.
