Problems with edge-triggered jk flip-flop [Copy link]

I didn't understand the difference between edge-triggered JK flip-flop and pulse JK flip-flop after reading the book?

Assuming that both receive signals from the trigger on the rising edge, are they the same?

When the main trigger is not blocked, does the edge-triggered jk trigger also need to look at all the states of the main trigger based on the jk signal to determine the state before the rising edge arrives? Or is it enough to just look at the state of the jk signal before the rising edge arrives?

Is it the same as the pulse trigger, that the main trigger can and can only flip once when activated?
