• True

• False

Flips-flops are wired together to form combinational logic circuits.

• True

• False

On a flip-flop, the complementary output (Q1) is always at the same logic state as the normal (Q) output.

• True

• False

The complementary output (Q1) of a flip-flop is always at the opposite logic state from the normal (Q) output.

• True
