Detailed Solution
Download Solution PDFConcept:
For a counter with ‘n’ flip flops:
- The total number of states = 2n (0 to 2n – 1)
- The largest number that can be stored in the counter = 2n – 1
To construct a counter with any MOD number, the minimum number flip flops required must satisfy:
Modulus ≤ 2n
Where n is the number of flip-flops.
Calculation:
Number no. of flip – flops are required to construct a mod-15 counter, must satisfy:
2n ≥ 15 i.e.
n = 4
