The output of the circuit can be given by Y= overline(A B) barC= barA+ barB+C If the output is zero, i.e. Y=0 then A=1 B=1 and C=0

Q. In the following circuit, the output $Y$ becomes zero for the input combinations

$A = 1, B = 0, C = 0$

$A = 0, B = 1, C = 1$

$A = 0, B = 0, C = 0$

$A = 1, B = 1, C = 0$

The output of the circuit can be given by
$Y = \overline{(A B) \overset{ˉ}{C}} = \overset{ˉ}{A} + \overset{ˉ}{B} + C$
If the output is zero,
i.e. $Y = 0$ then $A = 1$
$B = 1$ and $C = 0$

Q. In the following circuit, the output Y becomes zero for the input combinations

A=1,B=0,C=0

A=0,B=1,C=1

A=0,B=0,C=0

A=1,B=1,C=0
