SINOPSIS

The problem of determining the frequencies and amplitudes of sinusoids in an observed signal is considered. The procedure of solving of the system of linear algebraic equations is a main computational procedure of proposed algorithm, i.e., the proposed algorithm is not connected with the integration of the system of differential equations like some well-known algorithms. The case, when the signal under consideration contains one sinusoid and constant component, is considered in detail. The efficiency is illustrated by examples.
