PhysicsSingle correct+4 / -1Question 38 of 75

Two 4 bits binary numbers, $A=1101$ and $B=1010$ are given in the inputs of a logic circuit shown in figure below. The output ( $Y$ ) will be :

Y=1101

Y=0010

Y=0111

Y=1000

Answer and worked solution

Official answer: A

Logic. $Y=\overline{\bar A\cdot B}=A+\bar B$ .

Bitwise. $A=1101$ and $\bar B=0101$ , so $Y=1101$ .

(A)
