5 votes 5 votes $Y= A'B'C + A'BC' + AB'C' + ABC$ $Y= A\ xor \ B \ xor \ C$ $Y= \sum(1,2,4,6,7)$, difference equation of full subtractor. Hence Option d) is correct Ashwani Kumar 2 answered Jan 13, 2020 Ashwani Kumar 2 comment Share Follow See all 2 Comments See all 2 2 Comments reply Swaraj Dasgupta commented Jan 13, 2020 reply Follow Share Ans can be A also... 3 votes 3 votes rahul247 commented Feb 4, 2020 reply Follow Share There is a flaw in options , Both options (A) and (D) are correct. 0 votes 0 votes Please log in or register to add a comment.
2 votes 2 votes The output Y of the given MUX is the equation for the difference of a full subtractor and Sum of a Full Adder. Y is the difference between A and B where C is the Barrow. Y is the Sum of A and B where C is the Carry_in. Y = B’A’C + B’AC’ + BA’C’ + BAC Y = (A ⊕ B ⊕ C) topper98 answered Mar 21, 2020 topper98 comment Share Follow See all 0 reply Please log in or register to add a comment.
