A Filter Bank Solution to Absorption Simulation and Compensation

In this paper I present a digital filter bank solution to the problem of simulating or compensating the effect of absorption on seismic traces. I stay in the context of frequency-independent Q models for attenuation and dispersion. The key benefit of the outlined technique is that it can deal with arbitrarily time-variant Q i.e. is not limited to the case of mild variation of Q with time. Introduction Absorption simulation or compensation filtering in the context of this paper refers to the application of digital filters with the
