ON THE DECOMPOSITION OF SWITCHING FUNCTIONS
LOCKHEED MISSILES AND SPACE CO SUNNYVALE CALIF
A given switching function of n variables can frequently be decomposed into a composite function of several essentially simpler switching functions. Such decompositions lead to designs of more economical switching circuits to realize the given switching function. Ashenhursts chart method is generalized to nondisjunctive decompositions by means of the dont care conditions. This extension provides an effective method of constructing all decompositions of switching functions. Author
