  1. 4. ______ before a bracket flips the whole bracket's result. In (______ A) AND B, ______ flips only input A, so ______ gives different results. Word 1 of: ___ (A AND B) (3)
  2. 6. An extra truth table column for a bracket or gate output, such as P = A AND B. It is filled in first, so the final output X can be worked out step by step from earlier columns. Word 1 of: ____________ ______ (12)

  1. 1. Read the ______ for rows 00, 01, 10, 11 to name the gate: AND 0001, OR 0111, NAND 1110, NOR 1000, XOR 0110. Word 2 of: ______ ______ (6)
  2. 2. A small ______ on a gate's ______ means NOT: AND becomes NAND and OR becomes NOR. XOR has no ______; its symbol is OR with an extra curved line at the input side. Word 2 of: ______ ______ (6)
  3. 3. Word 1 of the term in 2 Down: ______ ______ (6)
  4. 5. The ______ (exclusive OR, or EOR) gate has two inputs and outputs 1 only when the inputs are different. Its truth table output is 0 1 1 0. Its symbol is the OR shape with an extra curve at the input. Word 3 of: X = A ___ B (3)
