Hello,
I'm trying to understand the attached schematic. It's supposed to be a positive-edge triggered JK flip-flop. As far as I know, it means that it's only reacting to commands during the positive-edge. So if there was a short jump command during CLK = 0 and Q = 0, nothing should happen - right?
However, the given schematic shows a positive-edge triggered JK flip-flop (made of D-flip flops). Now imagine Q = 0 and C = 0. Meanwhile a short J-command occurs. Wouldn't that mean: Immediately, the master-FF changes to 1? And as soon as C = 1, this state is passed to the slave?
I'm really confused, because this would mean you could change the flip-flip's state by sending a command during C = 0 - doesn't it?
Thanks in advance!
