  1. The divide by N counter is shown in figure. If initially Q0 = 1, Q.1 = 1, Q2 = 0. What is a value of N?
    1. 8
    2. 6
    3. 5
    4. 3
Correct Option: D

Given circuit arrangement

From given circuit arrangement, we get

i.e., After first CLK we get 2 → 1 → 4 again and again. Thus we can conclude that the given arrangement is known as Mod–3 counter. Hence alternative (D) is the correct choice.
