1. A signal processing apparatus, comprising:

  • signal output means for 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

    analyzing means for frequency analyzing a response signal obtained as a result of picking up the measurement signal output from the signal output means.
