Abstract :
The paper discusses the use of a fractional-rational approximation for estimation of the parameters of resonant oscillations if resonance frequencies are situated rather close with substantial overlapping. Limits of applicability of the method of fractional-rational approximation by continued fractions have been determined for two closely spaced resonances in presence noise.
