4-Bit Binary Counter

A 4-Bit Synchrnous Counter Using JK Flip-Flops

This counter is implemented using four JK Flip-Flops from Simulink Extras Flip Flops Library.
As input there is a constant Count Enable.
If it is set to 1 then the counter will be working, otherwise (on 0) not.
On 16 clock tick the Output Carry will be enabled. After that the counting will start all over again.
