Question

(i) A counter is needed to count the number of malt cans being filled automatically in a drink plant. A photocell and light source together are used to produce a single pulse each time a can crosses the path of this combination.Calculate the number of flip-flops needed if 1000 cans are to be counted.

(ii) A ripple counter which utilizes 4 flip-flops has a delay time (tpd) to be equal to 12ns. What can be the biggest mod-counter that can be made from the flip-flops considering that the frequency  at which it is operated is 10MHz?
