Notes: 1. H; high level, L; low level
2. Q0; The level of Q before the indidicated input conditions were established.
3. *; This output level is psodo stable; that is it may not persist when S and R inputs return to their inactive
(high) level.
4. **; For latches with double S inputs; H; both S inputs high, L; one or both S inputs low.
