ISRO2016-EC combinational logic
in given combinational logic $X=?$ $X = AB'C' +A'BC'+ A'B'C+ ABC$ $X = A'BC +A'BC'+ AB'C+ A'B'C'$ $X = AB + BC + AC$ $X= A'B'+B'C'+A'C'$
in given combinational logic $X=?$$X = AB'C' +A'BC'+ A'B'C+ ABC$$X = A'BC +A'BC'+ AB'C+ A'B'C'$$X = AB + BC + AC$$X= A'B'+B'C'+A'C'$
