Abstract
We discuss a method of data filtering for a resonant gravitational wav e detector that allows an optimal reconstruction of the input signal. The method consists of the estimate, by optimal Wiener filtering, of t he amplitude of the Karhunen-Loeve components of the signal at the ant enna input, and only needs the assumption that the signal has a finite duration. After discussing an application of the method to a simplifi ed model for a resonant antenna, we present a practical application to the reduction of the data from a room temperature antenna.
