Description

Resampling the seismic data

 

During the seismic data acquisition we record the data at sample interval say 2ms and we want to resample the data to 4ms for various reasons. By re-sampling we can reduce the number of samples that way we can minimize our data size without compromising the primary properties of seismic wavelet i.e., amplitude, frequency and phase. Re-sampling is beneficial up to certain sampling interval, above that it will degrade the seismic data by introducing aliasing. Resampling can be done in Frequency domain or using “sinc” function(sampling function).
