Abstract :
In operation the method of etalonless diagnostics of machines is offered on the basis of the analysis of vibroacoustic signals bound with unobservable errors of manufacture and operation. The part from errors has no adequate representation in dials of the ratio and intervals. The canonical coupling equation between diagnostic indications of a signal and structural state variables of the machine representing a bisectrix of the first angle of an information plane is deduced (removed), and the outcomes of model operation for a normal distribution are reduced
