The problem of synthesis of switching systems is one of ever increasing importance to modern technology; it arises in the design of digi¬tal computers, telephone switching systems and control mechanisms of all sorts. Be¬hind, in fact, every pushbutton lies a switching circuit. In spite of its considerable importance there is as yet no well developed theory for the rational design of such systems. In a book entitled Synthesis of electronic computing and control circuits, by the Harvard Computation Laboratory. Professor H-E. Aiken [A] states that a lack of adequate mathematical methods for the investigation of the functional behavior of electronic control circuits represented the largest single obstacle to the rapid de¬velopment of the subject.
