# Dictionary:Normalized phase

Other languages:
English • ‎español

The normalized phase is a seismic attribute. In some instances a black and white section with balanced amplitudes similar to those of the seismic section is required for interpretation. Conventional short window AGC application changes the reflected event characteristics; hence the interpreters do not favor them. The display without the change of these basic characteristics is the cosine of the Instantaneous Phase. This display has all the details of the instantaneous phase section and shows the desired lateral continuity. The display has no amplitude information and its envelope is constant unity.[1]

${\displaystyle ||\phi (t)||=\cos(\phi (t))}$
