Q64 / 90 · JEE Main 2016 (03 Apr) · Physics

If a, b, c, d are inputs to a gate and $x$ is its output, then, as per the following time graph, the gate is:

Correct answer
A
OR
B
NAND
C
NOT
D
AND

Solution

a	b	c	d	X
0	0	0	0	0
0	0	0	1	1

When any input is one, output is one, hence the gate is 'OR' gate.

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