1. A method for analyzing impedance with binary excitation said method comprising the steps of: a) generating a binary excitation signal and applying the signal to an object under test; b) receiving a response signal and initially analyzing the response signal; c) obtaining estimation parameters of the object by the initial analysis of the response signal in step b) and using the estimation parameters as input values for frequency characteristic estimation; d) generating parameters of a model, wherein the parameters are controlled by output results of the estimation of the parameters of the object under test; e) using waveform of excitation signal as an input and generating a model of initial analysis of the response signal, the model having parameters which are determined by the output result of the generation of the parameter of the model of step d), and f) estimating the parameters of the object under test, controlled by the output results of the model of the initial analysis of the response signal of step e); wherein in the analysis of the parameters of the object under test, the parameters are determined for the model, in which the results of the initial analysis of the response signal are maximally similar to the results of the model of the initial analysis of the response signal.
