The combination of NAND gates shown here in the figure give output C and C ' . C and C ' are equivalent to

Options

  1. AOR gate and AND gate respectively
  2. BAND gate and NOT gate respectively
  3. CAND gate and OR gate respectively
  4. DOR gate and NOT gate respectively

Correct answer

A. OR gate and AND gate respectively

Step-by-step solution

C = A ¯ ⋅ B ¯ ¯ = A + B Thus its OR gate C ' = A ⋅ B ¯ ¯ = A ⋅ B Thus its AND gate
