Need help with a counter for a jk flip flop thats uses a 12hr clock counter for the hours and minutes only. can someone show me the design of this plan starting with the truth table to the actual circuits design.

This sounds like a homework problem.

In that case, you need to show your work.

In any case, you need to put some effort into researching and understanding how to approach your question and make that evident to those you want help from.

Can someone check if what i'm doing so far is correct and i don't know how to implement the k-maps to draw the circuit.
