| Abstract(in English) | Generalized Harmonic Analysis (GHA) is equipped with excellent time-frequency resolution better than that of conventional Short Time Fourier Transform (STFT). This advantage is brought by the principle that GHA represents any signal with a combination of sinusoidal functions of inharmonic frequency relationship (Quasi-periodic function). However, its fundamental characteristics such as frequency separation or measurement errors are not clarified sufficiently. The authors investigated measurement errors through applying the GHA to test signals consist of two sinusoidal functions of different frequencies and amplitudes. Consequently, it was made clear that the errors are observed as variations of amplitudes and frequencies, which depend on frequency difference and amplitude ratio between two signals of sinusoidal functions. Furthermore, it was clarified that the error is caused by an interference from undesirable frequency components in the observed signal band mixed from the other signal, and the interference are estimated with the inner product of two signals. |
