Praca związana jest z problematyką przetwarzania sygnału pomiarowego z przepływomierza wirowego. W szczególnych konstrukcjach i sytuacjach pomiarowych sygnał może być słabej jakości. W pracy opisano algorytm dekompozycji empirycznej sygnału i analizę spektralną wyekstrahowanej składowej podstawowej. Przeprowadzono badania empiryczne, które wykazały efekt mieszania się częstotliwości. Zastosowany zmodyfikowany algorytm pozwolił na eliminację wpływu tego efektu na wynik przetwarzania.

The work is related to the problem of the vortex flowmeter signal processing. In specific flowmeter designs and measurement circumstances, the signal might be weak. Algorithm of empirical decomposition of the signal and spectral analysis of extracted fundamental component has been described. The effect of frequency mixing has been observed in empirical investigations. Due to modified algorithm application, suppression ofthis effect has been attained.(Hilbert-Huang transform application in vortex meter signal processing)
