On the synthesis of nonlinear time-invariant networks

This correspondence considers the design of a class of uncoupled nonlinear time-invariant networks operated in the small-signal mode. A necessary and sufficient condition is stated under which, for a given set of "slowly varying" bias sources, the characteristics of the nonlinear network can be obtained so that the behavior of the approximate small-signal equaivlent network is identical with the behavior of a prescribed linear time-varying network. A third-order example has been worked out to illustrate the method.
