General principle of electrical equivalence for nonuniform transmission lines

Abstract

The criterion of electrical equivalence for nonuniform transmission lines, introduced by Hellstrom, has recently been interpreted in a more general form. The letter presents the electrical-equivalence principle' in a simple manner. It is shown that any nonuniform RC (or LC) line may be made electrically equivalent to another RC (or LC) line, if the physical lengths of the two lines are properly chosen.
