If a momentary '1' is applied at the set (S) input of an RS flip-flop with both inputs initially at 0, what will happen to the output Q?
If a momentary '1' is applied at the set (S) input of an RS flip-flop with both inputs initially at 0, what will happen to the output Q?
- Q will remain at 0
- Q will flip from 0 to 1 and then back to 0
- Q will oscillate between 0 and 1
- Q will flip from 0 to 1 and stay there (correct)
