@@ -226,30 +226,35 @@ The initial status of the D flip-flops in the absence of the clock signal is Q2Q
 Similarly, the following operations take place for every positive edge of the clock signal.
 - Serial input of first D flip-flop gets the previous complemented output of the third flip-flop. So, the present output of the first D flip-flop is equal to the previous complemented output of the third flip-flop.
 - The previous outputs of first and second D flip-flops are right shifted by one bit. That means, the present outputs of second and third D flip-flops are equal to the previous outputs of first and second D flip-flops.
