Technological method for the design of measuring instruments and systems for operation in previously unknown operating conditions

The method of designing radio engineering systems and measuring instruments, which are not affected by disturbing influences, is presented. The method is developed on the base of dual channel principle, formulated by academician Petrov B.N. The technique of practical realization of this method is considered. The advantage of the method is that it allows compensating disturbing influences, nature of which is not known in advance. The efficiency of the method and its implementation technique are illustrated by dual channel measuring bridge circuit. The importance of correct metrological analysis, which confirms efficiency of the method, is shown.
