Abstract
An algorithm has been proposed to evaluate optimal parameters of sinusoidal and exponential models of a dis-crete signal segment. It has been shown that the algorithm can be applied to evaluate the time-frequency distribution of a quasi-harmonic signal. An example is presented of time-frequency distribution calculation of a real signal ob-tained on the laboratory facility "Mayatnik" (pendulum).
