METHOD OF PICKING UP USEFUL SIGNAL OF PROCESS BEING CARRIED OUT Russian patent published in 2010 - IPC G01M7/00 G01R23/16 

FIELD: physics.

SUBSTANCE: in a method of picking up a useful signal when carrying out a process, which involves narrow-band filtering of this process with subsequent detection of the filtered signal and its comparison with a threshold value, as well as computer processing of the process, narrow-band filtration is carried out through automatic frequency tuning of the corresponding filter, where frequency tuning ends when the level of the picked up signal reaches the threshold value, after which a computer processing control signal of the process is generated. Broadband filtration of the process is then carried out. The invention enables pick up of useful signals having coherent features when carrying out a stationary random process and provides hardware processing of signals in the time and frequency domain.

EFFECT: more accurate determination of complex dynamic processes during laboratory experiments.
