METHOD OF PULSE SIGNAL ISOLATION BY TIME DATA Russian patent published in 2015 - IPC G06F17/14 

FIELD: physics.

SUBSTANCE: proposed method comprises registration of signal composed of the additive sum of signals of systems ensemble. It is subjected to threshold rectification with further alignment of all pulses with amplitude exceeding the threshold level. Characteristic pulse shapes of every system corresponding to peaks of scale factor distribution density of the first main components are defined. Optimum set of parameters maximizing the differences between characteristic pulse shapes in wavelet-factor space is defined. Wavelet-conversion factors are calculated. Then, pulses are filtered with the help of low-pass filter by characteristic pulse shaped of every system. Filter frequency cut-off is defined in the range of 100-150 Hz proceeding from maximization of differences between said shapes in wavelet factor space.

EFFECT: pulse signal isolation by time data.
