METHOD FOR PROCESSING AND ANALYZING MEASUREMENT SIGNALS COMING FROM ENTITY UNDER CHECK (ALTERNATIVES)

摘要

instrumentation and computer engineering. SUBSTANCE: method involves spectral analyses of measurement data signal and measurement check signal with comprehensive frequency spectrum at all time spaces. Check signal is subjected to spectral analysis within entire range or at separate frequency components of spectrum of analyzed measurement data signal. Comparison results of spectrograms or separate frequency components of spectrum of analyzed measurement data signal under check and measurement check signal are used to identify distorted portions or separate frequency components of spectrum which are excluded from further analyzing process. EFFECT: improved confidence of analyzing results. 2 cl, 5 dwg, 3 tbl
