SIGNAL PROCESSING SYSTEM Russian patent published in 2013 - IPC G01M7/02 G01R23/165 

FIELD: test equipment.

SUBSTANCE: signal processing system containing a filter re-tunable as to frequency is characterised by the fact that the system includes a vibration test complex, an anaylser, a visual monitoring instrument, a shaper of a non-stationary process, a control signal source and a strobing unit; with that, the first input of the filter is connected to the output of the vibration test complex, and the output is connected to the input of the visual monitoring instrument, the first and the second output of which are connected to the first and the second inputs of the analyser respectively, the third input of which is connected to the first output of the shaper of the non-stationary process, which is connected at the same time to the input of the vibration test complex; with that, the fourth input of the analyser is connected to the first input of the system, and the output is connected to its output; with that, the second output of the shaper of non-stationary process is connected to the first input of the strobing unit, the output of which is connected to the second input of filter, and the second input of which is connected to the output of the control signal source, the input of which is connected to the second input of the system.

EFFECT: improvement of processing accuracy.
