Condition to avoid race around problem:

where, Δt = Pulse width
T = Period of pulse
2t_p = Propagation delay of two NAND gates or flip-flop.
It may be noted that t_p is the propagation delay of one gate. However any flip-flop made up of 4 NAND gates or NOR gates, and any input passes through 2 gates, that's why here we must take 2t_p propagation delay.

Correct Option: B

14 × (16)¹ + 5 × (16)° = 229 = decimal equivalent (E)₈ = (14)₁₀ Hence alternative (B) is the correct answer.

Correct Option: B

14 × (16)¹ + 5 × (16)° = 229 = decimal equivalent (E)₈ = (14)₁₀ Hence alternative (B) is the correct answer.

NA

Correct Option: B

NA

As we don't know the value of Q = 1 or 0, so there can be 2 possible sequence.

Hence, modulo cannot be determined unless other information regarding initial value of Q given.

Correct Option: D

As we don't know the value of Q = 1 or 0, so there can be 2 possible sequence.

Hence, modulo cannot be determined unless other information regarding initial value of Q given.
