Abstract
A signal processing method includes generating N data sequences by dividing i-th measurement data based on a signal output from an i-th sensor that detects a physical quantity generated due to a vibration of a target object, for each integer i of 1 or more and M or less, where N is a predetermined integer of 2 or more, and M is a predetermined integer of 2 or more, generating an i-th averaged data sequence by averaging the N data sequences generated by dividing the i-th measurement data, for each integer i of 1 or more and M or less, and generating a Lissajous figure in which the i-th averaged data sequence is assigned to an i-th axis, for each integer i of 1 or more and M or less.
