Comparisons of the identification of mathematical macromodels in three metrics-Gaussian, Chebyshev, L1

The problem of mathematical macromodelling is describes. The results of macromodelling using approximations by the methods of least squares, chebyshev and L
₁
approximation for the frequency detector, multivibrator and oscillator is presented. The expediency of the method of least squares to reproduce the original signal macromodels of nonlinear electronic devices are demonstrates.
