Overview

Course objective

• Introducing the student to the types of geophysical signals and the method of measuring them.

• Teach the student the difference between analog recording and digital recording.

• Teaching the student sampling theory.

• Teach the student how to calculate the oscillation, periodic time, wavelength, wavenumber and velocity and how to calculate them.

• How to perform shifts, flips and gradations of digital signals.

• How to convert signals from the temporal domain to the stereoscopic and atomizing domains using mathematical equations.
