Thread: Multiplexer question

hi everyone,

Want to find out how to reduce this equation to 3 inputs, A,B & D:

A’B’C’D + A’BC’D’ + A’BC’D+ A’BCD+ AB’C’D+ AB’CD+ ABC’D+ ABCD = Z

tq & rgds..

Hi everyone,

A’B’C’D + A’BC’D’ + A’BC’D+ A’BCD+ AB’C’D+ AB’CD+ ABC’D+ ABCD

only managed to get this:

A’B’D +C'+ A’BD’ + C'+ A’BD+C'+ A’BD+C+ AB’D+C+ AB’D+C+ ABD+C'+ ABD+C

=A’B’D+A’BD’+A’BD+AB’D+ ABD+C'+C'

pls advise.....
