Question

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 gate circuit is:(a) OR gate(b) NOR gate(c) AND gate(d) NAND gate

Answer 1

The answer would be A or B

Answer 2

Answer:

A) OR gate

Explanation:

Inputs of the logic circuit = A and B

Output = C

The relation between input and output  is described as Y= A+B

wherein  A and B are input  and Y is output.

On the basis of given diagram, the following table is possible.

Input - A   0 1 0 1

           B   0 0 1 1  

Output C    0 1 1 1

This truth table obtained is of OR gate . Hence logic gate circuit is OR gate
