Refer to the logic circuit given below. For two inputs (

A = 1, B = 1

) and (

A = 0, B = 1

), output (Y) will be ______.

Answer: (C)

The inverter produces

\overset{ˉ}{A}

. The OR gate gives

\overset{ˉ}{A} + B

and the AND gate gives

\overset{ˉ}{A} \cdot B

; both feed the final NOR gate, whose output is

Y = \overline{(\overset{ˉ}{A} + B) + (\overset{ˉ}{A} \cdot B)} = \overline{\overset{ˉ}{A} + B} = A \overset{ˉ}{B}

. For

A = 1, B = 1

Y = 1 \cdot \overset{ˉ}{1} = 0

. For

A = 0, B = 1

Y = 0 \cdot \overset{ˉ}{1} = 0

. The outputs are

0, 0

respectively.
