Abstract

An explicit formula was derived for the maximum entropy spectrum. The characterization of state-covariances of continuous-time filters based on filter parameters was also studied. It was found that input spectra, which are consistent with a given state covariance of a linear filter, correspond to solutions of an analytic interpolation problem.
