Logic gates

Question

The following figure shows a logic gate circuit with two inputs A and B and the output C. The voltage waveforms of A, B and C are as shown below. The logic gate is

Moderate

A

OR gate
B

AND gate
C

NAND gate
D

NOR gate

Solution

from the waveform it is observed that when
A=0, B=0 $\Rightarrow$ C=0,
A=1, B=1, $\Rightarrow$ C=1,
A=0, B=1, $\Rightarrow$ C=1,
A=1, B=0, $\Rightarrow$ C=1.
the logic circuit is an OR gate
