You tie the D input to the /Q output to get it to toggle.JK flip flop with J and K tied together is like a D type ff

Wiki is good on jk ff's
its jk flip flop with positive edge triggered flip flopFor a JK flip-flop:
Q goes to 1 when J is 1 after the appropriate clock edge and stay there.
Q goes to 0 when K is 1 after the appropriate clock edge and stay there.
Q alternates its state when both J and K are 1 after the appropriate clock edge.
You need to know whether the FF changes state on the rising edge or the falling edge of the clock. Knowing that, you can then complete the table from what is stated above.

1 0 ↑ Q Q0
1 1 ↑ 1 0
is it correct ?
