If a, b, c, d are inputs to a gate and x is its output, then, as per the following time graph, the gate is:

Options

  1. AOR
  2. BNAND
  3. CNOT
  4. DAND

Correct answer

A. OR

Step-by-step solution

a b c d X 0 0 0 0 0 0 0 0 1 1 When any input is one, output is one, hence the gate is 'OR' gate.
