    • Abstract
  • The method of suppressing 50 Hz industrial interference is mainly to use notch filter to filter in the frequency domain, which not only suppresses signals of 50 Hz interference, but also damages the effective signal, thereby degrades the quality of seismic data.In this paper, the interference amplitude and phase characteristics of the 50 Hz industrial noise were obtained by using the iterative method to analyze the signal before the first break wave.The practical application shows that this method can effectively suppress the 50 Hz interference and does not harm the effective signals.
