| Abstract: | Aiming at improving the accuracy of vibration signal analysis,a method based on the full period re-sampling technology was established.The full period sampling time calculated by the frequency synchronously sampled with the vibration signal was used to re-sample the waveform.And each channel was compensated with the error phase generated by loop sampling between channels.The study shows that this method can re-sample the vibration signal in periods correctly and increase the accuracy of amplitude and phase.... |
