g-Platform provides several radon modules: Band-pass filter,Band-pass Butterworth,Time-varying band-pass filter,Band-pass filter (Distributed).

 

                     Band-bass filter                    

This module works in the frequency domain and has a single bandpass filter mode, for the entire trace length, specified as four corner frequency values F1-F2---F3-F4. In the frequency domain application, the amplitude spectra of the input seismic trace and the filter operator are multiplied. The main goal of using band-pass operator is passing limited amplitudes via the cut-of frequencies. Where F1-F2 is the first damping slope, F2-F3 is maximum band pass and F3-F4 is the second (end) damping slope.
