Question

In the following digital circuit, what will be the output at ${}^{\prime }{Z}^{\prime }$, when the input $(A,B$) are $(1,0),\text{are}(1,0),(0,0),(1,1),(0,1)$

• A. $0,0,1,0$
• B. $1,0,1,1$
• C. $1,1,0,1$
• D. $0,1,0,0$

Answer 1

The correct option is A $0,0,1,0$

A	B	$\overline{A.B}$	$\overline{A+B}$	$W=\left(\overline{A.B}\right).\left(\overline{A+B}\right)$	$Q=W+\overline{A.B}$	$\overline{Q}=x$
1	0	1	0	0	1	0
0	1	1	0	0	1	0
1	1	0	0	0	0	1
0	0	1	1	1	1	0
