Question

What is velocity filter???

Answer 1

A velocity filter removes interfering signals by exploiting the difference between the travelling velocities if desired seismic waveform and undesired interfering signals.

Answer 2

The velocity filter is defined as follows:

• The difference between the travelling velocities of the desired seismic waveform and undesired interfering signals is exploited by a velocity filter to remove interfering signals.
• Unlike multi-channel filtering, which produces a one-dimensional output, velocity filters provide a two-dimensional output.
• It has already proven to be a reliable and practical alternative to pure magnetic analysis.
• When paired with either electric or magnetic deflection methods, it can be used to examine a beam that is non-homogeneous in mass and velocity.
