Terminal Configurations of n-Port Networks
Abraham Lempel, Israel Cederbaum · IEEE Transactions on Circuit Theory · 1968
In this paper, bounds on the number of port terminals for families of equivalentn-port networks are discussed. Classes ofn-ports, for which no equivalents with less than2n-1terminals exist, are demonstrated. It is shown that upper bounds (less than2n) on the number of terminals also exist. These may not exceed, in certain cases, even the minimum number ofn + 1terminals. Finally, some incomplete results on related problems are presented.
