ধারণা:

একটি 'n' ফ্লিপ ফ্লপ কাউন্টারের জন্য,

  • পরিস্থিতির মোট সংখ্যা = 2n (0 to 2n – 1)
  • বৃহত্তম সংখ্যা যা কাউন্টারে সংরক্ষণ করা যেতে পারে = 2– 1

যেকোন মোড কাউন্টার তৈরি করতে, ন্যূনতম সংখ্যার ফ্লিপ ফ্লপ প্রয়োজন যেমন: মডুলাস ≤ 2n

যেখানে n হল কাউন্টারের সংখ্যা।

উদাহরণ স্বরূপ,

একটি MOD-5 কাউন্টারে প্রয়োজন:

  2n ≥ 5 

∴ 3 ফ্লিপ ফ্লপ

গণনা:

mod-12 কাউন্টার তৈরি করার জন্য প্রয়োজনীয় ফ্লিপ-ফ্লপের সংখ্যা নিম্নরূপে পাওয়া যায়:

2n ≥ 12 অর্থাৎ n = 4
