An application of Boolean algebra to the design of electronic switching circuits

IN THE 15 years since Shannon1 introduced the Boolean algebra as an aid towards the analysis and synthesis of switching circuits, this algebra has proved to be a worthwhile addition to the procedures available to the switching circuit designer. Although, in its present form, it cannot be employed to solve many of the problems by which the designer is confronted, the switching algebra provides an exceedingly effective technique in those cases where its use is indicated.
