    • Abstract
  • Some approaches by digital filtering in the processing to earthquake generated converted waves are discussed in this paper. Lowpass filtering,polarization filtering,frequence weighting filtering,correlation filtering,and superposition processing are used to improve the resolving power of seismic records and to raise the signal-to-noise ratio,and so the possibility of phase identification of PS coverted waves is greatly improved.
