संकल्पना​:

'n' फ्लिप फ्लॉप काउंटरसाठी,

  • स्थितींची एकूण संख्या = 2n (0 to 2n – 1)
  • सर्वात मोठी संख्या जी काउंटरमध्ये संग्रहित केली जाऊ शकते = 2– 1

 

कोणतेही MOD काउंटर बांधण्यासाठी, फ्लिप फ्लॉपची किमान संख्या आवश्यक आहे जसे की: मॉड्यूलस ≤ 2n

जेथे n ही काउंटरची संख्या आहे.

उदाहरणार्थ,

एका MOD-5 काउंटरसाठी आवश्यक आहे:

  2n ≥ 5 

∴ 3 फ्लिप फ्लॉप

गणना:

MOD 12 काउंटर बनवण्यासाठी आवश्यक असलेल्या फ्लिप फ्लॉपची संख्या:

2n ≥ 12 i.e. n = 4
