On the precision of the identification of systems based on RC equivalent circuits

A model example for estimation of the precision of Kronecker–Chebyshev and Kronecker–Chebyshev–Akhiezer identification algorithms in the frequency domain based on RC equivalent circuits is described. The advantages of the proposed algorithms for identification problems are noted. Such problems usually include rational approximation of functions, where these functions are specified by the values of the results of measurements at fixed frequencies.
