I had a task making asynchronous MOD-14 down JK counter, only problem is that it turned out to be synchronous, can you help me modify the counter to make it asynchronous? Thank you in advance, any help is needed

 

Asynchronous counters are easy; as long as they count in the normal sequence. Do you know the rules for count down (or up)?

Rules for counting down are 1101, 1100... 0000 then again 1101. Or do you mean something else by rules for counting down/up?

The rules tell you how to connect flip flops to count down based on the polarity of their clocks.
