In recent years Boolean Algebra has come to play a prominent role in the
analysis and synthesis of switching circuits [1; 4]. One general synthesis
problem in which this algebra has proved useful is the following. Let there
be given n input leads each of which can assume one of two possible states.
It is desired to construct a network with these n input leads and a single
output lead also capable of assuming either of two states. Furthermore, the
state of the output lead for each of the 2n states of the input
leads is prescribed.
