          <datacite:description descriptionType="Abstract">本論文には,周波数測定により,二本だけ存在する周波数線スペクトルの包絡線の中心局波数を推定する方法を考察してある.始めに,二つの正弦波の振巾比が,その合成波の周波測定により求められる事を示し,次に,その振巾比より,スペクトル包絡線の中心を推定する方法について考察してある.</datacite:description>
          <datacite:description descriptionType="Other">In this paper the method of estimating the envelope center of two pieces of line spectra by frequency measurement is studied. Namely it is shown that the amplitude ratio of two sinusoidal waves is obtained by measuring the frequency of the resultant wave and that the method of estimating the envelope center of the spectrum is considered by use of the amplitude ratio.</datacite:description>
