Abstract

We observe a record consisting of a "signal" plus "noise" up to the time instant t, and wish to extract the value of the signal at the time instant (t+m) by mean of a linear filter. We consider the case where both signal & noise processes are non-stationary. In this paper the filtering problem has been considered when the evolutionary spectrum has been estimated.
