Question

What logic function does the circuit produce if an AND gate feeds into a NOT gate?
  1. A
    OR gate
  2. B
    NAND gate
    Correct
  3. C
    NOR gate
  4. D
    XOR gate

Correct answer

NAND gate

Explanation

AND followed by NOT = NAND: Y = (A·B)̄. This is the definition of a NAND gate. Similarly, OR followed by NOT = NOR gate.
