PL Trudnym do rozwiązania problemem diagnostyki technicznej jest pomiar sygnałów otoczenia. W wielu przypadkach pomiar ten jest niemożliwy. Stąd podjęcie problemu eliminacji otoczenia z procesu identyfikacji progów diagnostycznych jest zasadne. Przedstawiony sposób eliminacji otoczenia polegający na pr[...]
EN Measurements of signals received from ambient environment is a difficult task for technical diagnostics and becomes even infeasible in a series of cases. It is why the issues related to elimination of ambient factors from the identification process of diagnostic thresholds are truly justified. The m[...]
