The present output Qn of an edge triggered JK flip flop is logic O. If J = 1, then Qsub>n + 1
-
- cannot be determined
- will be logic O
- will be logic 1
- will race around
Correct Option: C
Since given that Qn = 0
and j = 1, the output Qn + 1 will be logic 1
whatever the value of k i.e., either 0 or 1
if k = 0, then flip-flop becomes set and output
Qn + 1 goes to logic 1, and if k = 1, then the flip-flop will toggle to 1. So in both the case Qn + 1 will be logic 1.
