Two-level logic using NAND and NOR gates

• de Morgan's law

  • Standard form: A'B' = (A + B)' A' + B' = (AB)'
  • Inverted: A + B = (A'B')' (AB) = (A' + B')'
  • AND with complemented inputs ? NOR
  • OR with complemented inputs ? NAND
  • OR ? NAND with complemented inputs
  • AND ? NOR with complemented inputs
