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


A
NAND gate
B
OR gate
C
NOR gate
D
AND gate
Detailed Solution
Reading the waveforms gives the truth table (A, B → C): 0, 0 → 0; 1, 0 → 1; 0, 1 → 1; 1, 1 → 1
The output is 1 whenever at least one input is 1, which is the truth table of an OR gate.
The output is 1 whenever at least one input is 1, which is the truth table of an OR gate.
