Peculiarities of magnetic resonance signals processing during the express control of the liquid media state

The paper discusses the need to develop a new approximation of the nuclear magnetic resonance signals. This approximation allows enhancing functional capabilities of express control devices. The universal mathematical model is developed to describe the shape of the NMR signals taking into account the peculiarities of their registration using a modulation technique in a weak field. The modeling results obtained are compared with experimental data. (paper)
