I've just learned how to make a counter from JK flip flop. Exciting! :)
At this stage I'm trying to fix the display glitch caused by the propagation delay with a buffer at bottom.
Adding a few inverters at left bottom side in order to delay the buffer update didn't help much. But this shouldn't be noticeable in a real circuit and I'm not sure it is worth fixing it because it will add extra cost. But if there's a simple solution to it please let me know, I'm really curious what are the possible solutions.
