PROCESSING OF SIGNALS IN A FMR THE METHOD OF THE MAXIMUM CREDIBILITY.
In the given work the theory of optimum reception in the appendix to signals of a ferromagnetic resonance is considered. The question on increase of the permission of two signals is solved with close resonant frequencies. It is shown that at consecutive application of the theory of optimum reception resolution will be defined not by criterion of Relej, and the relation a signal/noise and frequency of digitization of readout in sample of the data. By means of modeling calculations comparison resolution for a method of the maximum credibility and for a classical method (transformation of Fure) has been spent. The following is received: at factor of correlation of two signals more than 0,09, classical method processings are given by an error, and at factor of correlation more than 0,5 signals become indiscernible. The method of the maximum credibility authentically defines signal parameters even at factor of correlation of an order 0,9. Also the analysis of a noise stability of a method of the maximum credibility has been carried out. Result of research: at the relation a signal/noise ~6 дБ parameters of two signals are defined authentically. At fall of the relation a signal/noise to-3,5 дБ frequencies also are defined authentically.
