Analysis of rotating machines

摘要: System and method for analyzing an input signal acquired from a physical system with rotating element. A tachometer is received comprising rotation speed information the time sequence determined using signal, values element at substantially equal angle increments, e.g., by edge detection software or timer/counter. software-based first digital interpolation filter, Cascade-Integrator-Comb applied to sequence, generating modified sequence. digitized data increments. second filter which re-sampled generate domain where usable analyze system.
