The application of the parameters of the modes of signal allocated using the extremal filtering algorithm is considered. The use and disadvantages of amplitude detectors are described. Use of attenuation are described and shows how to reduce the effect of ""overshoots"". It is proposed to use a combined sign for a more contrast extracting of detection areas. A method for reducing the labor intensity is presented, which consists in applying filtering directly to a number of extrema, without calculating the smoothed components.A method was chosen that allows the signal analysis algorithm to be adapted to work in real time.

Described is method Extreme filtration. Given justification applying extreme filtering using the time-lapse signal processing method for real-time systems. Shown principle of operation of the method is and the features of its application are described. Are given results of modeling work in the Matlab environment.
