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

Options

  1. AOR gate
  2. BNOR gate
  3. CAND gate
  4. DNAND gate

Correct answer

A. OR gate

Step-by-step solution

From the given woveforms, the following truth table can be made This truth table is required to 'OR' gate. So, logic circuit gate is OR gate. Note The logic of the OR gate is if any of the input is one then output is one.
