Q. 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 circuit gate is

A) AND gate
B) NAND gate
C) NOR gate
D) OR gate
Explanation

(a) From truth table it is clear that output is high if at least one input is low. The Boolean expression which satisfies the output of this logic gate is $C = A \bullet B,$ which is for AND gate.
