if a,b,c,dare inputs to a gate and x is ...

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 :
d
c
ba
x

A

NAND

B

NOT

C

AND

D

OR

Text Solution

Verified by Experts

The correct Answer is:
D
Output of OR gate is 0 when all inputs are 0 & output is 1 when atleast one of the inputs is 1. Observing putput x :- It is 0 when all inputs are 0 & it is :- 1 when atleast one of the inputs is 1
`:.` OR gate.
