t0 के दौरान सभी Q मान शून्य पर सेट होते हैं,

इसलिए

और

बढ़ते किनारे के दौरान Q1 = D का पिछला मान अर्थात 1 और Q2 = Q1 का पिछला मान अर्थात 0 (10)

⇒ वर्तमान स्थिति D = 1 ⊕ 1 = 0

इसी प्रकार अगले क्लॉक पल्स के लिए Q1 = 0 और Q2 = 1 ⇒ D = 0 (01)

अगले पल्स के लिए Q1 =0 Q2 = 0 ⇒ D = 1 जो कि प्रारंभिक स्थिति है (00)

इसलिए अनुसरण किया गया क्रम 10, 01, 00, 10…… है।
