Abstract:

In order to improve the use of multiplexer for combinational logic circuit design methods, the multiplexer and or formal logic expressions of the output function is analyzed. The relationship between output function and output inverse function is mutually inverse. For some design can make the data input variables of the multiplexer be the original, without the need for additional gate to take the operation of the variable, simplify the circuit structure.

Key words: multiplexer, output function, logical not function, logic design
