5.5 BAND-PASS FILTER 261

FIG. 5.19 Workflow for band-pass filtering process in (A) frequency and (B) time domains. (C) Filtering is performed either
using multiplication ( ) of the amplitude spectra of the raw seismic and filter operator in the frequency domain (upper panel),
or by a convolution (*) of the seismic data itself with the filter operator in the time domain (lower panel).
