The basic problems encountered in network theory are generally classified as problems in either network analysis or network synthesis. In analysis one generally desires to determine the response of a given network to a prescribed excitation. In this case the result is unique requiring only time and patience to grind out the answer. The problem of network synthesis is much more subtle in fact, it is really two problems. Initially, one must deal with what has been called the approximation problem. This is the problem of finding an appropriate rational algebraic expression that satisfies the specified response to a prescribed excitation. Once this is accomplished the designer must then obtain an equivalent network. There are two inherent considerations related to the overall synthesis problem that distinguish it from analysis. First, is the question of the existence of a solution, and secondly, the solution is not unique. We are concerned here with a device that is an aide in the solution of the approximation problem and provides a rapid answer to the analysis problem.
