Irredundant and Redundant Boolean Branch-Networks

Abstract
Certain Boolean functions can be generated by irredundant branch-networks, i.e., with networks with only one branch for each variable (literal) of the function. A simple solution (based on graph theory) is given to the realizability problem for irredundant 2- andn-terminal networks. The theory of irredundant networks is significant for the design of redundant networks, i.e., networks generating functions with a certain protection against temporary branch errors. A few examples on redundant networks are given and the method of design is compared with coding theory.
