A certain JK flip-flop has tpd = 12·5 ns. The largest MOD

A certain JK flip-flop has t_pd = 12·5 ns. The largest MOD counter that can be constructed from these flip-flops and still operate upto 10 MHz is—

Clock period =	1	= 100ns
	10 × 10⁶

∴

Number of flip-flop =	100(ns)	= 8
	12.5(ns)

∴ Maximum MOD counter = 256 ∴ (2⁸ = 256)
