Apparatus, method and program for processing signal and method for generating signal

A signal processing method, comprising steps of:

• outputting a measurement signal, the measurement signal being produced by synthesizing a signal composed of a concatenation of 2d period signals with a sinusoidal wave signal, each period signal having a time-domain waveform period being 2n samples, the sinusoidal wave signal having a wave count within a concatenation period of 2d period signals being other than an integer multiple of 2d, and n and d being natural numbers;
• and
• frequency analyzing a response signal obtained as a result of picking up the output measurement signal.
