Abstract
An important step in the synthesis of sequential switching circuits is the assignment of binary variable states to represent internal states of the circuit. A formula is derived here which indicates the number of different assignments which can be made for flow tables having a given number of rows. There are only three essentially different assignments possible for a four-row table, and there are 140 for a five-row table.Keywords
