INTERPRETATION OF BUTTERWORTH (BANDPASS) FIlLTERING

Abstract

The basic purpose of the present work is to understand th e seismic ftltering procedure with the special emphasis on the Butterworth (band pass) ftl tering. The basic approach o f interpretation is practical. l ntuitive (and theoreti cally sound) arguments arc used to explain the theory with extensive examples . .Implementation of Butterworth fIltering was carried out both in the tirne domain and frequency domain. The amplitude response Improves as the order of Butterworth Etlter increases. Higher Butterworth order means higher slopes and ideal filte ring can be achieved.
