| Abstract(in English) | Given a signal s(t) composed of two signals s_1(t) and s_2(t) having different fundamental frequencies F_<01> and F_<02>, a method to extract the spectrum of s_1(t) or of s_2(t) is reported. Spectrum smoothing by convolving the power spectrum of s(t) with a Bartlett window whose length is 2F_<01> gives a spectral envelope without any effects of F_<01>, but directly related to F_<02>. The spectrum of s_2(t) can be extracted because its effect on the smoothed spectrum is propotional to the amplitude of its harmonic components. Such an extraction of spectrum is not achieved by an enhancement of the harmonic components as one group, but by a cancellation of the spectral components of the other group. In this report, spectral distortions of the extracted spectrum of s_2(t) are computed, and the capabilities and limitations of the method are discussed. An implementation to onset detection is also reported. |
