A model is proposed for describing the line shape of absorption and dispersion signals from which a recorded signal of nuclear magnetic resonance (NMR) is formed in a weak field. The expediency of using spectral analysis to determine the contributions of absorption and dispersion signals to the recorded NMR signal has been substantiated using a modulation technique. A new method is proposed for determining these contributions. The research results are presented.
