Hey guys, i designed a 3bits gray counter with a control to switch from upward and downwardn using flip flop T, i use multisim to mount the circuit and instead of flip-flip T i use flip flop JK with with the same input in J and K. My question is, how the Preset and CLear work on the Flip flop? First i use and flip flop with just Clear and it works fine in the simultaion but when i mount the circuit the count will get stuck. I attached the word i create with the truth table and an image of the circuit i try to simulate using FF-JK with CLear and Preset.
