Which logic gate is represented by the following combination of logic gates?

Options

  1. AOR
  2. BNAND
  3. CAND
  4. DNOR

Correct answer

C. AND

Step-by-step solution

y 1 = A - , y 2 = B - y = y 1 + y 2 ¯ = A ¯ + B ¯ ¯ Using De-Morgan's theorem y = A ¯ + B ¯ ¯ = A . B So, it is AND gate Truth table: A B y 1 y 2 y 0 0 1 1 0 0 1 1 0 0 1 0 0 1 0 1 1 0 0 1
