The modified criterion of optimization for coefficients of an adaptive filter with final impulse response using an information about a velocity of change of an error of adaptation is offered and investigated. The possibility of application on an analysis interval of recursive algorithm Levinson-Durbin, permitting to carry out optimization of filter coefficients in a real time scale is proved. The effectiveness of the offered criterion for minimization of an error signal dynamic range on a filter exit is shown on an example of handling of a speech signal.
