10. What is the logic equation for the output Z for the state diagram of the previous question if the following state assignments are given: a = 00, b = 01, c = 10, d = 11. (Note: these are the Y1Y2 codes for the states a, b, c, d)

  1. Z = X (Y1) (Y2)
  2. Z = X(Y1) (Y2)
  3. Z = X(Y1)Y2
  4. Z = XY1(Y2)
  5. Z = XY1Y2

2 is WRONG. Consider what conditions must hold in order that Z = 1 (Hint: Must be in state d and X must be 1)
