| 1. A method for determining improved impedance coefficients of a seismic trace, the method comprising the steps of:
determining reflection coefficients of the seismic trace;
integrating the reflection coefficients with respect to time, to obtain impedance coefficients; and
filtering the impedance coefficients by applying a low-cut window filter.
