INTERPRETATION

Abstract

FOURIER TRANSFORM PLAYS A KEY ROLE IN INTERPOLATION OF SEISMIC SECTIONS. FOURIER TRANSFORM ENABLES THE INTERPRETER TO EXTRACT THE FREQUENCY DATA WHICH IS NEEDED FOR REALIZING VARIOUS STRUCTURES. NON-STATIONARY SIGNALS BEHAVE EXTREMELY DIFFERENT THOUGH. WHEN WE ARE FACING A NON-STATIONARY SIGNAL, FINDING THE TIME-FREQUENCY MAP BECOMES A BIT COMPLICATED. THAT IS WHEN THE SHORT TIME FOURIER TRANSFORM (STFT) COMES IN HANDY. WE WILL DISTINGUISH THIS DIFFERENT BEHAVIOR OF NON-STATIONARY SIGNALS THROUGH THIS TEXT, AND WILL EXAMINE STFT IN PRACTICE.
