Hi,

Have checked the boolean expression in vol 4.
link: http://www.allaboutcircuits.com/vol_4/chpt_8/8.html

The examples has the output of
Out = (A+B+C+/D)(A+B+/C+D)(A+/B+C+/D)(A+/B+/C+D)(/A+/B+/C+D)(/A+B+C+/D)(/A+B+/C+D)

but i think it should be like this.
Out = (A+B+C+/D)(/A+B+/C+D)(A+/B+C+/D)(A+/B+/C+D)(/A+/B+/C+D)(/A+B+C+/D)(/A+B+/C+D)

The 2nd expression should have A bar on the top.
note: I used "/" as Bar on the top of the letter.
If the expression is wrong then the computation should be changed.

Thanks.

Those were the formulas to simplify, the starting condition. Why and how could the question be wrong? Are you disagreeing with the solution to the problem?

I don't see it myself.
