The Band-Pass Analysis feature in g-Viewer enables users to analyze the frequency spectrum of seismic data by selecting specific areas within a dataset.

Multiple Selections Within a Single Seismic Dataset enables users to select multiple regions within a single seismic dataset for spectrum analysis.

Workflow:

• Open a seismic dataset in g-Viewer.
• Activate the Band-Pass Analysis tool at the top of the view
• Select multiple regions of interest within the seismic data using left mouse button
• Each selected region will be analyzed, and its corresponding frequency spectrum will be plotted

Spectral Analysis Panel

Once selections are made, the spectral analysis panel displays:

• The list of selected regions.
• The computed amplitude spectrum for each selection.
• The option to change color, the same color will be highlighted a rectangle on Seismic data view and show spectrum plot
• Options to adjust frequency smoothing and zoom settings.
• Export functionality for saving results.

Calculation Settings

• Smoothing: Adjusts the level of spectral smoothing.
• Max Frequency: Defines the upper limit of the analyzed frequency range.

Zoom & Display Options

• Users can zoom into specific frequency ranges.
• The "Auto fit zoom" feature optimizes the view for better visualization.

Users can analyze the frequency spectrum using different types of spectral analysis:

• Amplitude: Displays the amplitude of each frequency component.
• Phase: Shows the phase shift of each frequency component.
• Energy: Represents the energy distribution across frequencies.
• dB: Provides a decibel scale representation of spectral content.
