The output of the given combination gates represents:

Options

  1. AXOR Gate
  2. BNAND Gate
  3. CAND Gate
  4. DNOR Gate

Correct answer

B. NAND Gate

Step-by-step solution

By De Morgan's theorem, we have Here the output of A and B gives A ¯ and B ¯ . This output is fed as inputs to NAND gate and the output is A · B , when when again fed as input to NAND gate to get output as A · B ¯ .
