Here you have the output of an AND gate connected to the Q output of a JK FF. Not allowed!
Why use JK? & you cant leave JK inputs floating.
Where's the truth table or whatever that describes the functionality - impossible to decipher from schematic - so no way to validate.
Where are the gate designations, how do we differentiate them? " third gate down, fourth from left" doesn't work for me!
What are the devices with arrows and a floppy disc symbol?
