FIELD: information and measurement systems f aircraft and power plants. SUBSTANCE: process of measurement of physical quantity lies in its conversion to output signal of N pickups, in computation of optimal parameters of N filters and in their tuning. Output signals of pickups are filtered and value of measured physical quantity is obtained by summation of filtered signals. Characteristic feature of process consists in computation of N differences of output signals of pickups, in computation of correlation functions of difference signals for q a priori specified correlation intervals and in determination of a priori known correlation functions of errors of conversion of physical value by each pickup which are used for computation of optimal parameters of filters. EFFECT: increased precision of measurement of physical quantity.
