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.
