a The MOD number of a counter is equal to the number of comp

(a) The MOD number of a counter is equal to the number of complete states that a counter goes through before it recycles back to its starting state. To construct a ripple counter with a MOD number X, it requires a minimum number of N FFs such that 2N ? X. What is the maximum MOD # of a counter constructed with 6 flip-flops? (b) Counters with a MOD number larger than 16 can be created by cascading 4-bit binary counters. The MOD number is equal to the product of the individual MOD numbers. For example, a MOD 80 counter can be implemented as shown in the following figure (general block diagram, all of the wiring is not shown).

Solution

a.Max mod=2^N=64 mod counter

b.for 16mod counter 4-flipflops is required for above 16mod we use cascade four bit flip-flops that gives the better result..,
