0 votes 0 votes Let f=AB+AB’+A’C+AC =A(B+B’)+C(A+A’) =A(1)+C(1) =A+C So,it is unaffected by the value of B option(2) Nilesh_01 answered Jul 23, 2021 Nilesh_01 comment Share Follow See all 0 reply Please log in or register to add a comment.
0 votes 0 votes Here f(A,B,C)=AB+AB'+AC+A'C After minimzation we get f= A+C that means f is independent from var. B . In other word ,here var. B is useless or dummy var(not standard term) Shubham_cse answered Oct 14, 2023 Shubham_cse comment Share Follow See all 0 reply Please log in or register to add a comment.
