We consider the problem of measuring of the resonance frequency according to the amplitude-frequency characteristic of a resonator with the help of the method of stochastic approximation (SA). Various modifi cations of SA algorithms in the MATLAB software are investigated for a computer model of resonator with given parameters. The influence of the parameters of SA algorithms, noise, and the Q-factor of the resonator on the accuracy of measurements and the rate of convergence is analyzed. We also perform the comparative analysis of the indicated modifications of the algorithms.
