A 4 bit synchronous counter uses flip flops with a delay time of 15 ns

1.	A 4 bit synchronous counter uses flip flops with a delay time of 15 ns each. The time required for change of state is
Answer» In a synchronous counter clock input is applied to all flip flops simultaneously. Hence total delay time is 15 ns.
