The figure shows a logic circuit with two inputs A and B and the output C. The voltage wave forms across A, B and C are as given. The logic circuit gate is:
OR gate
NOR gate
AND gate
NAND gate
As we learnt in
OR gate -
Relation between input and output
- wherein
A and B are input
Y is out put
From given wavefrom, the following truth table can be made.
Input | Output |
A B 0 0 1 0 1 1 0 1 |
C 0 1 1 1 |
This truth table obtained is of OR gate . Hence logic gate is OR gate.

Option 2)
NOR gate
This is incorrect option
Option 3)
AND gate
This is incorrect option
Option 4)
