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:

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:
  1. OR
  2. NAND
  3. NOT
  4. AND

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.
