A Combinatorial-Digital Computation of a Network Parameter

Abstract

In order to avoid numerical iteration in the calculation of a typical return-loss coefficient of an <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LC</tex> ladder structure, combinatorial analysis methods are used to form equations which defer inclusion of the problem data until an advanced stage in the solution. Three different combinatorial procedures are included. The network parameter calculation serves as a convenient example to demonstrate these combinatorial methods and the applicability of digital computers to combinatorial procedures.
