Question
A JK flip flop has t_pd= 12 ns. The largest modulus of a ripple counter using these flip flops and operating at 10 MHz is
Options
A. 16
B. 64
C. 128
D. 256

Correct Answer

256

Explanation

Number of flip-flops =

A JK flip flop has tpd= 12 ns. The largest modulus of a ripple counter using these flip flops and op

= 8.333 say 8

Modulus = 2⁸ = 256.
