Abstract

APPARATUS, METHOD AND PROGRAM FOR PROCESSING SIGNAL AND METHOD FOR GENERATING SIGNAL A signal processing apparatus includes a signal output unit for outputting a measurement signal, the measurement signal being produced by synthesizing a signal composed of a concatenation of 2 d period signals with a sinusoidal signal, each period signal having a time-domain waveform period being 2 n samples, the sinusoidal wave having a wave count within the concatenation period of 2 d period signals being other than an integer multiple of 2 d , and n and d being respectively natural numbers, and an analyzing unit for frequency analyzing a response signal obtained as a result of picking up the measurement signal output from the signal output unit.
