Q.
The figure (i) shows a logic gate circuit with two inputs $A$ and Band output $C$ . The voltage waveforms of $A,B$
$andC$ are shown in figure (ii) below.
What can you infer about the type of logic gate ?

Solution:
In above diagram $A$ and $B$ reprsent input signal and $C$ reprsent output signal.
Truth Table
A B C 0 0 0 1 1 1 0
1 0 1 0 0
From above Truth Table it is clear that the logic gate is $AND$ gate.
In above diagram $A$ and $B$ reprsent input signal and $C$ reprsent output signal.
Truth Table
| A | B | C |
| 0 | 0 | 0 |
| 1 | 1 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
