Design of linear time-varying and nonlinear time-invariant networks

Abstract

This paper considers the design of linear time-varying networks and of nonlinear time-invariant networks, the latter being operated in the small-signal mode. In the first part, the design example considered is a network whose time delay is a prescribed function of time. A quadratic performance criterion 'is formulated and the design is obtained iteratively by steepest descent. The second part of the paper considers the design of a nonlinear timeinvariant network with variable bias sources whose small-signal equivalent network is identical with a given linear time-varying network. Explicit conditions are given under which this can be done.
