A REVIEW OF METHODS OF FILTERING SEISMIC DATA

Abstract

Filtering in its general sense represents an important phase of data processing. In recent years such new methods as delay line filtering and digital filtering as well as conventional seismic filtering have been described in the literature. The purpose of this paper is to clarify the relationship between these methods of filtering and to compare design criteria such as cross‐correlation filtering and zero‐phase filtering. Synthetic records as well as field records are used to illustrate the effects of the various filtering techniques.
