In this work the synthesis of the algorithms for adaptive nonlinear signal processing in tracking meters implemented using the nonlinear blocks (NLB) based on the use of robust approach to determine the optimal parameters of amplitude transfer characteristics (ATC) at the finite signal/noise ratio (SNR) at the input is carried out. A robust approach to determining the minimum root mean square error (RMSE) and by the minimum criterion of the generalized (GRMSE) parameters of the NLB with the finite SNR is considered. The structural diagrams of the NLB, that implement the above-mentioned algorithms including the use of multidimensional quadrature generator, is presented. It is shown the difference signal from the useful, the ratios of their parameters and usage in this case, the probabilistic algorithm of Newtonian type. It is shown that the same adaptation algorithm can be used both for minimization of signal isolation and for minimization of GRMSE.
