0 votes 0 votes The output F = xy'z + w'xz + w'yz K-map of the above equation is So output in minimized form will be F= xy'z + w'yz, which we can get from logic gate 1 and 3, so logic gate 2 is redundant here. stblue answered Aug 11, 2017 stblue comment Share Follow See all 0 reply Please log in or register to add a comment.

Becoz in 3 rd gate given ~wxz= for cannonical ~wxyz+ ~wx~yz Similarly for gate 1 cannonical form is wx~yz + ~wx~yz And for gate 2 ~wxyz + ~w~xyz As you can see both the terms of 3rd gate can be derived using gate 1 and gate 2 so gate 3 is redundant here.
