Signal generation apparatus, signal generation program and signal generation method

Abstract

A signal generation apparatus includes an extraction unit and a conversion unit. The extraction unit is configured to extract part of a frequency waveform as an extracted waveform. The frequency waveform is a waveform represented by a function of frequency. The part of the frequency waveform corresponds to frequencies satisfying a preset extraction condition indicating that amplitude of the frequency waveform is high. The conversion unit is configured to convert the extracted waveform extracted by the extraction unit into a time waveform, which is a waveform represented by a function of time, and generate the time waveform as a signal.
