Q34 / 237 · NTA Abhyas (NEET) 2020 · Physics · Semiconductors

To get an output $1$ from the circuit shown in the figure, the input must be

A
$A = 0, B = 1, C = 0$
B
$A = 1, B = 0, C = 0$
Correct answer
C
$A = 1, B = 0, C = 1$
D
$A = 1, B = 1, C = 0$

Solution

The Boolean expression for the given combination is output

Y = (A + B) . C

Hence,

A = 1, B = 0, C = 1

or other combination can be

A = 1, B = 1, C = 1

Hence, the correct answer is option: 'C'.
