1. n. [Geophysics]
A process or algorithm using a set of limits used to eliminate unwanted portions of seismic data, commonly on the basis of frequency or amplitude, to enhance the signal-to-noise ratio of the data or to achieve deconvolution.

2. vb. [Geophysics]
To remove undesirable portions of data during seismic processing to increase the signal-to-noise ratio of seismic data. Filtering can eliminate certain frequencies, amplitudes, or other information.
